It breaks wind directions into 16 categories, with wind speeds grouped into different ranges, shown in varying shades of blue. The labels (N, NE, E, SE, S, SW, W, NW) provide a clear directional reference, making it easy to interpret wind patterns. This visualization highlights dominant wind directions and their intensity, offering valuable insights for applications like air quality studies, aviation safety, and urban planning. The Wind Rose Diagram shows that the wind primarily blows from the Southeast (SE) and Northwest (NW), making these the dominant wind directions in the area. The strongest winds, reaching around 7.7 m/s, come from the Southeast (SE), indicating a significant prevailing wind from this direction. Moderate wind speeds, around 5-6 m/s, are common in the Northeast (NNE) and East-Southeast (ESE) directions, reflecting steady but less intense airflow. Lighter winds, around 2-4 m/s, are recorded in the South-East (SE) and North-Northwest (NNW) regions, suggesting weaker wind activity. Interestingly, there are no calm wind conditions, meaning air movement is constant in some direction. This has important implications for air quality management, urban development, and wind energy potential.

Thursday 6 February 2025: Evening Carbon Monoxide (CO) Concentration (5:006:00 PM) Discussion From the analysis of the CLINE-4 model outputs, one can see that there are clear variations in mean carbon monoxide (CO) concentrations at the Qatar University campus based on time of day as well as day of the week. Studying the diurnal variations, the records reflect that though the largest number of motor vehicles pass through the campus during the morning hours (1,332 vehicles), the highest mean CO concentration is registered at noon at 5.99 ppm. This indicates that traffic volume alone is not responsible for CO concentrations, but factors like higher temperatures at noon (22°C versus 20°C at morning) and lower wind speed (5.66 m/s at noon versus 7.20 m/s at morning) increase the effectiveness of pollution dispersion, thus raising the mean CO concentration. Conversely, the morning hours, though suffering the highest vehicular flow, has the least mean CO concentration (5.21 ppm), due to the stronger ventilation resulting from higher wind velocities. The evening hours depict the declining mean CO concentration (5.63 ppm), corresponding to the huge decrease in the number of vehicles (to 300), suggesting that the drop in emission outweighs the lower wind velocity (4.12 m/s) effect on pollutant dispersion to result in lower mean CO concentrations. Examining the fluctuations between the workdays (Sunday to Thursday), the CLINE-4 model results indicate fairly consistent mean CO levels between the days, with the range spanning only between 5.48 ppm on Sunday to 5.76 ppm on Tuesday. This indicates the fairly constant amount of activity and resultant emissions throughout the average workweek. These slightly lower mean values measured on Sunday and Thursday likely reflect lower overall activity on these days than the more active mid-week period. The implications of such findings are substantial and call for the enforcement of targeted mitigation measures to ensure the well-being and health of the community at Qatar University. Although the modeled highest 1-hour CO level at Sunday (6.30 ppm) was less than the WHO 1hour target of 8.7 ppm (WHO, 2021), the mean CO levels throughout the week consistently exceed the WHO 8-hour mean target value of 3.5 ppm (WHO, 2021). This constant exceedance is likely to cause potential adverse effects to the human health due to long-term CO exposures, as indicated by earlier studies (Brook et al., 2010; Gurjar et al., 2010). Hence, preventive measures are urgently needed, such as optimizing traffic flow, with careful focus around peak hours of the day, specifically high-activity areas, encouraging, inducing, and promoting the use of alternative modes of transport to minimize vehicular exhaust, and integrating real-time atmospheric information into the overall air quality monitoring framework to facilitate adaptive management decisions based on informed inputs. Barcharts Figure 1: Comparison of CO Levels: Morning, Noon, and Evening Figure 2 Comparison of Average CO Levels Across Weekdays (Sunday to Thursday) Discussion The analysis of the outputs of the CLINE-4 indicates different patterns of average concentrations of carbon monoxide (CO) at varying times of the day and weekdays at Qatar University. Diurnal pattern (Figure 1) shows that even with maximum motor vehicle flow during the day (1,332 vehicles, according to earlier text), maximum average CO is observed at noon (5.99 ppm). That this is related to reasons other than mere vehicle flow, like higher temperature at noon (22C vs. 20C) and lower wind speed (5.66 m/s vs. 7.20 m/s), is evidenced by the fact that there is less effective pollutant dispersing at this time. The minimum average of the morning (5.21 ppm) in spite of maximum vehicles is an indication of better ventilation due to higher winds. Decrease in the evening average CO (5.63 ppm) goes along with an appreciable fall in vehicles (300) as emission reduction is greater than poorer dispersion (4.12 m/s wind speed). The daily variation (Figure 2) indicates fairly constant average CO levels, varying from 5.48 ppm (Sunday) to 5.76 ppm (Tuesday). This is indicative of uniform levels of activity and emissions across the workweek. The slightly weaker averages on Sunday and Thursday may reflect less overall activity than on mid-week days. A comparison with World Health Organization (WHO) guidelines indicates that although the modeled maximum 1-hour concentration on Sunday (6.30 ppm) was less than the 1-hour guideline value of 8.7 ppm (WHO, 2021), average levels at various times throughout the weekdays consistently exceed the 8-hour mean guideline value of 3.5 ppm (WHO, 2021). This correlates with the previous results and indicates a possible risk for chronic health effects of long-term CO exposure (Brook et al., 2010; Gurjar et al., 2010). These results have important implications for the implementation of focused mitigation actions. The diurnal and weekday patterns of CO concentrations unveiled by the modeling require proactive action. The high average levels consistently over WHO's 8-hour guideline (WHO, 2021) indicate an emergent chronic health risk to the campus community (Brook et al., 2010; Gurjar et al., 2010). Peak exposure mitigation and reductions of sustained levels across weekdays are key priorities for target-oriented strategies. Optimizing flow of vehicles, especially around high-activity areas, and offering incentives to adopt sustainable travel to minimize vehicle emissions are essential. References Brook, R.

Background and Literature Review (1-2 pages) 1.1.Background Carbon monoxide (CO) is a significant air pollutant resulting from vehicular emissions, posing health and environmental concerns, especially in urban areas with heavy traffic (EPA, 2020). As motor vehicles are one of the primary sources of CO, understanding its dispersion along roadways is crucial for effective air quality management and public health. Vehicular emissions contribute substantially to the urban air pollution problem, particularly in developing countries where traffic congestion and aging vehicle fleets exacerbate the issue (Karner, Eisinger, & Niemeier, 2010). The CALINE4 model, developed by the California Department of Transportation, is a widely used air quality dispersion model specifically designed to predict CO concentrations near roadways (Benson, 1992). This model considers factors such as wind speed, traffic volume, road geometry, and emission rates, making it a valuable tool for evaluating CO dispersion patterns. When combined with Geographic Information Systems (GIS), CALINE4 can provide a spatially detailed analysis of CO pollution, helping researchers, policymakers, and urban planners to identify high-risk areas and implement effective mitigation strategies (McNally et al., 2015). The integration of GIS with the CALINE4 model enhances the model’s ability to simulate complex environments by providing geospatial data on road networks, land use, topography, and meteorological conditions. This approach allows for a more comprehensive analysis of CO dispersion, making it possible to assess the impact of different scenarios, such as changes in traffic flow or road Senior Project Proposal Template Department of Biological and Environmental Sciences configurations, on air quality (Abdul-Wahab, 2004). As urban populations continue to grow, understanding and modeling vehicular CO pollution dispersion is essential for developing sustainable transportation systems and ensuring public health and safety. 1.2.Literature review The relationship between vehicular emissions and air pollution has been a subject of extensive research over the years. Motor vehicles emit various pollutants, including CO, nitrogen oxides (NOx), particulate matter (PM), and hydrocarbons, which contribute to poor air quality, particularly in urban environments (Zhu, Hinds, Kim, & Sioutas, 2002). CO, a colorless and odorless gas, is primarily produced by the incomplete combustion of fossil fuels, and prolonged exposure can lead to severe health effects, such as headaches, dizziness, and even death at high concentrations (World Health Organization, 2018). 1.2.1. Overview of Vehicular Pollution Dispersion Vehicular pollution is a critical concern in urban areas, primarily due to its impact on human health and the environment (Chen et al., 2020). Various studies have demonstrated that pollutants emitted from vehicles, such as carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM), and volatile organic compounds (VOCs), contribute significantly to the deterioration of air quality (Seinfeld & Pandis, 2016). The dispersion of these pollutants depends on numerous factors, including meteorological conditions, road configurations, traffic volume, and vehicle types (Kumar et al., 2015). Understanding these factors is crucial for predicting pollutant concentrations in different urban environments and for formulating effective mitigation strategies. 1.2.2. Dispersion Models for Vehicular Pollution The modeling of vehicular pollution dispersion is an important tool for understanding the way in which roadways spread their pollutants into the surrounding environment. Such models can simulate the transport of a pollutant-their CO, NOx, and PM-with variables related to wind speed, temperature, and traffic density (Vardoulakis et al., 2003). These are quite enlightening with regard to air quality and important in regulatory assessments and urban planning. Gaussian models, such as CALINE 4, are among the most common dispersion models used for pollutant dispersion prediction in urban areas. In fact, the development of such models was based on the Gaussian plume theory, where pollutant dispersion takes a bell curve due to atmospheric conditions (Zannetti, 1990). Other powerful models dealing with complex environmental factors include topography and surface roughness, AERMOD, which quite often is applied in combination or for comparison with CALINE 4 (U.S. EPA, 2004). Such models do field simulations of actual conditions for the understanding of dispersion and accumulation of pollutants; hence, data useful in traffic management and control of pollution. 1.2.3. Application of CALINE4 in Dispersion Modelling CALINE 4 is a roadway Gaussian dispersion model specifically designed to predict the concentration of vehicular emissions near roadways. Developed by the California Department of Transportation, it simulates the dispersion of pollutants such as CO, NOx, and PM, considering factors like vehicle type, speed, traffic volume, and meteorological conditions (Benson, 1989). CALINE 4 finds a wide range of applications in environmental impact assessments and urban planning due to its abilities in simulating various pollution levels from roads, intersections, and parking lots with respect to distances. The model has been used in various studies related to the prediction of air quality impacts in urban settings. For instance, it is often applied in the assessment of pollution concentrations around schools, residential areas, and other sensitive receptors along major highways. -Benson, 1992. It is especially useful for analyses of the impact of traffic congestion on air quality, because it accounts for both moving and Senior Project Proposal Template Department of Biological and Environmental Sciences idling vehicles. It also works with current software, including CALRoads View, to bring convenience in handling big data volumes and complicated situations in the simulation of the flow of vehicles. 1.2.4. Integration of GIS in Air Quality Modeling The use of GIS technology in air quality modeling has gained popularity due to its ability to manage, analyze, and visualize spatial data. When combined with models like CALINE4, GIS can provide detailed insights into pollutant dispersion patterns across different geographic regions (Abdul-Wahab, 2004). For instance, a study by McNally et al. (2015) demonstrated the effectiveness of using GIS with CALINE4 in evaluating CO pollution dispersion in an urban setting, enabling researchers to identify pollution hotspots and assess the impact of traffic management strategies. Additionally, it can enable real-time integration of information with traffic and meteorological data for dynamic updating of models in pollution aspects, thereby increasing prediction accuracy manifold to make informed decisions on urban planning and policy matters. 1.2.5. Limitations of the CALINE4 Model Aside from its popularity and efficiency, CALINE 4 possesses a number of limitations. In the model, it is presumed that it works on a steady-state condition, which means it cannot account for the variation in emission with time since the amount of traffic flow changes at different hours of the day. According to Benson (1992), this is considered to be one limitation of the model regarding the accurate modeling of dynamic traffic flow, especially at the peak time of traffic. Though the model is designed to predict pollutant dispersion in open countryside, it may not simulate air quality in complex environments such as areas with high-rise buildings or with varying topography accurately. The simplistic model treatment of urban canyons or areas with sharp changes in terrain may lead to localized under or over-estimation of pollutant concentrations. Another limitation is its inability to handle reactive pollutants like ozone, O3, because it cannot handle the chemical reaction within the air. It becomes less applicable, therefore, for studying secondary pollutants that are generated through chemical transformation in the air 1.2.6. Future Directions in Vehicular Pollution Modelling The future development of vehicular pollution modeling works toward greater accuracy and adaptability to diverse urban scenarios. Hybrid models, which couple Gaussian dispersion methods with either computational fluid dynamics or machine learning methodologies, could become potential options for handling such complex environments and dynamic traffic conditions (Wang et al., 2020). In this way, such methods would be better able to incorporate real-time variation in traffic, changes in meteorological conditions, and urban obstructions like buildings and tunnels. Recently, there has been a growing interest in integrating real-time traffic and meteorological data with emission models for highly accurate predictions. These tools are able to use real-time traffic data from sensors or cameras with cutting-edge dispersion algorithms that provide more accurate and local predictions of air quality. (Sun et al., 2020). Finally, vehicle electrification and the increasing use of zero-emission transportation will redefine the emphasis of future modeling efforts. As vehicular emissions composition shifts, models will have to adjust to new pollutants, such as those associated with tire wear or production of used electricity for electric vehicles (Hooftman et al., 2018).

How does traffic volume impact CO concentration levels along roadways? 2. How effective is the integration of GIS with the CALINE4 model in predicting CO dispersion patterns? 3. What role do meteorological conditions play in the dispersion of vehicular CO pollution? 2.4.Significance Understanding the dispersion of vehicular CO pollution is crucial for developing effective traffic management and air quality control measures. This research will provide valuable insights into how traffic volume, meteorological conditions, and road configurations impact CO levels along roadways. The integration of GIS with the CALINE4 model offers a powerful tool for spatial analysis, enabling policymakers and urban planners to identify pollution hotspots and implement targeted interventions to improve air quality and protect public health. 3. Research Materials and Methods (3-5 pages) The materials used in this study include the CALINE4 air dispersion model software, GIS software (such as ArcGIS), traffic volume data, emission factors, and meteorological data. The CALINE4 model, originally developed by the California Department of Transportation, is essential for simulating CO dispersion patterns along roadways (Benson, 1992). The GIS software will be used to manage and analyze spatial data, allowing for the visualization of CO concentration levels across the study area (Abdul-Wahab, 2004). Traffic data, including vehicle counts, speeds, and fleet composition, will be obtained from traffic monitoring agencies, while emission factors will be sourced from emission inventory databases, such as the EPA's MOVES (Motor Vehicle Emission Simulator) model (EPA, 2020). Meteorological data, such as wind speed, wind direction, temperature, and humidity, will be collected from nearby weather stations to account for their influence on CO dispersion (Hagler et al., 2009). This combination of data sources and modeling tools will provide a comprehensive analysis of CO pollution along roadways, contributing to improved air quality management strategies.

Figure 1. shows Qatar map precisely Qatar University Senior Project Proposal Template Department of Biological and Environmental Sciences 3.3.Data collection The monitoring of air quality will be performed using a land-use/land cover map where sampling points are to be selected strategically. These sampling points are to be selected such that air quality across regions with the majority of the vulnerable population can be represented. Data will be collected across several locations along Qatar University Road for comprehensive study of vehicular activity in these critical areas and of carbon monoxide emissions and this will be measured over five continuous days to get real and representative data; this also means that it is a continuous and consistent data set. Monitoring will be carried out during peak hours of traffic congestion-from 7:30 AM to 9:00 AM in the morning, between 1:30 PM and 3:00 PM in the afternoon, and from 5:00 PM to 7:00 PM evening. These time slots correspond to the morning and afternoon rush hours traffic when traffic volume is at its peak, and thus carbon monoxide emissions from vehicles are also likely to be high. The study will focus on these periods so that the maximum impact of traffic on air quality can be captured. Data to be collected would include vehicular carbon monoxide levels, the volume of traffic passing each monitoring point. The nature of the analysis may be done in such a way that the correlation between traffic density and air quality on Qatar University Road is elaborated. It analyzes the data of successive days peak traffic, attempting to find regularity and correlation within the aspect of vehicle emissions with respect to road traffic flow. Such information is crucial in understanding the environmental impact of vehicular traffic; thus, it will enable academics and policymakers to develop urban planning and traffic management policies. However, apart from the field data, secondary data will be sought from the Ministry of Environment that has two air quality monitoring stations currently operating in Doha. The latter information, while useful for validation purposes, is insufficient to result in comprehensive spatial interpolation, so additional data collection shall be undertaken by the research team with the help of air pollution meters. It will also include meteorological data, which will provide information on wind direction, speed of wind, temperature, and altitude-all these being factors that affect the dispersion of pollution. Complementing this, relevant spatial and non-spatial data, including administrative boundaries, population statistics, land use/land cover maps, and road networks, will be obtained from Qatar GISNet to account for holistic air quality over this area. 3.4.Data Entry and Geocoding Sampling locations will be determined randomly, taking into consideration the land use types mentioned in section 3.3. Students will receive training from faculty members on the methods for geographically sampling locations. These locations will then be pinpointed using a handheld GPS device. Students will visit these sampling locations to collect air quality data using ArcGIS Survey123, which will enable direct data logging into the ArcGIS format. Data on the pollutants mentioned in section 3.3 will be gathered using an air pollution meter. Addioinallly, the data will be aggregated and transmitted in real time to a central database, where it shall be analyzed and visualized immediately to present the level of pollution in the study area, hence enabling the identification of temporal patterns and emerging trends of pollution. Senior Project Proposal Template Department of Biological and Environmental Sciences 3.5.Analysis A Land Use/Land Cover (LULC) cluster map for the study area will be generated using data from the Qatar GISNet, and students will classify this map following the criteria outlined in section 7.2. Air pollution levels across the study area will be modeled using the CALRoads View software, developed by Lakes Environmental Software and approved by the US Environmental Protection Agency (EPA). This software integrates meteorological parameters with pollutant levels to create a comprehensive air pollution map for each pollutant (Diem & Komrie, 2002; Beelen et al., 2009). High pollution areas for each parameter will then be identified based on national and World Health Organization (WHO) standards, with potential pollution sources also being determined. Additionally, a population density map for the study area will be created and correlated with the air pollution maps. An overlay analysis combining the population density data with the composite air quality map will be performed to identify pollution hotspots in residential and sensitive areas. 4.

Training skills I took an internship at MECC, I also got practical experience in current analysis and monitoring in the Air Quality Department. The section responsible for Ambient Air Quality maintains the three fixed stations within Qatar: Al Corniche, Aspire Zone, and Qatar University, apart from mobile stations, which can be mobilized at any moment against emergencies. These monitor the critical pollutants of CO2, SO2, NO2, CO, O3, particulate matter (PM2.5, PM10), among others. Each station has a series of analyzers linked to computers that provide current air quality data, which in turn are networked with the Ministry for automatic recording and evaluation. The Air Quality Department takes this data to evaluate the Air Quality Index, which determines the grade of pollution in a given area at any moment.

Introduction A. One use plastics are man-made substances that do not occur naturally on our planet. Because of their unnatural form, the Earth itself is ill-equipped to break down this abnormality and return these substances back into the earth. Therefore, plastic persists on our planet and causes disruptions to ecosystems thus making plastic a convenience device that is proving to have compounding negative effects to our planet. What’s your topic? Why is it important and why should it be addressed? 1. ? source: (Stuart, 2019), (Woldemar, 2019) B. Plastic was first created by chemist Leo Baekeland in 1907. However, it was the 1970’s when plastic use exploded. Traditional glass and paper packaging started rapidly being replaced by plastic for its durability and cost effectiveness. Thus the convenient, throw away culture was born. Provide relevant background information 1. ? source: (Rhodes, 2018), (EPA, 2024) C. Single use plastics were born out of convenience. Humanities' need for packaging, storing, and transporting items in light-weight containers made living easier for people. However, once we have the plastic, we don’t manage its waste well. Approximately, “8.4% of waste plastics are successfully recycled, 75.8% are landfilled, and 15.8% are incinerated” (Chea et al. 2023). How has this problem emerged? 1. ? source:(Chea et al. 2023), (Woldemar, 2019) D. One-use-plastics pollute our planet's land and waterways as well as being a direct detriment to human health as well as other organisms. Plastics “physically break into smaller particles in marine environments, whereby they enter into food chains” (Stuart, 2019). Those “tiny pieces of plastic have been found in tap and bottled water, in salt, beer and honey, in oysters, clams, mussels, crabs, lobsters, and even inside us”. What are some of the major impacts associated with this issue? 1. ? source:(United Nations 2022), (Stuart, 2019) E. Plastic pollution is a GLOBAL problem. An “estimate that of the 8.3 billion tons (Bt)of plastics produced from 1950 to 2015, 5.7 Bt were waste, 4.9 Bt of which were discarded into landfills or the natural environment, such as oceans and waterways ”. (Stuart, 2019). Over the past 20 years the manufacturing of plastic has doubled. Currently, the world is not dealing with the overproduction of plastic. Although international conversations are starting with countries, there is a desperate need for firm policies to end the overuse of plastic world wide. What is the current status? 1. ? source: (Stuart, 2019), (EPA, 2024) II. Pillar of Sustainability - Environment A. Although plastics have impacted land and freshwater ecosystems, marine ecosystems have been hit the hardest. What ecosystem is most affected by your issue? 1. ? source: (NOAA, 2023), (Woldemar, 2019) B. Plastic is littering marine coastlines worldwide and marine life is being harmed as they are entangled in plastic and unfortunately consume it as well. “Kuhn and van Franeker found that over 700 species, including seabirds, fish, turtles, and marine mammals, have been confirmed to eat plastic.” (NOAA, 2023). How/Why is the ecosystem affected? 1. ? source: (NOAA, 2023), (Woldemar, 2019) III. Pillar of Sustainability - Economics A. The state of New Jersey has passed a law that states “ retail stores, grocery stores and food service businesses may not provide or sell single-use plastic carryout bags and polystyrene foam food service products.” (NJDEP, 2022). Additionally, The United Nations is currently writing a global treaty for the world to curb its plastic usage and production. Are there any regulations in place affecting your issue? 1. ? source: (United Nations, 2022) , (NJDEP, 2022), (Rhodes, 2018) B. “Plastics have the advantage of a high strength-to-weight ratio, allowing minimal material usage (and low cost) in packaging design” (Andrady & Neal, 2019) . This “minimal material usage” also leads to lower transportation costs. Ultimately, the consumer pays less for the product as compared to products shipped in glass or other heavier options. How are economics and money tied to your issue? 1. ? source: (Andrady & Neal, 2019), (Rhodes, 2018) C. Plastics make life easier by providing inexpensive ways of packaging products. “Plastics support the long supply chains of the modern food system by preserving food, extending transportation time and shelf life, and enabling the mass production and long-range distribution of foodstuffs” (Yates & ela., 2025). Thus providing an ease to living conditions everywhere. How does your issue affect human standards of living, poverty, etc? 1. ? source: (Yates & ela., 2025), (Andrady & Neal, 2019) IV. Pillar of Sustainability - Social/Human A. Humans demand a convenient and easy life. Plastics answer the call. Human demand for plastic products drives the massive manufacturing output of one-use-plastics. Yet, at the same time, the aftermath of plastics pollute the environment that we live in. How do humans cause or are influenced by your issue? 1. ? source: (Rhodes, 2018), (Stuart 2019) B. Although plastics are seen as a convenience, a way of life for humans, we need to be aware of the harm that plastics are really doing to us. According to the United Nations “exposure to plastics can harm human health, potentially affecting fertility, hormonal, metabolic and neurological activity” (United Nations 2022). How does your issue affect human health, happiness, or education? 1. ? source: (United Nations 2022), (Yates & ela., 2025) C. Poorer countries feel the impact of plastic pollution more than other countries. “Developed economies with regulations that encourage it have recycling rates around 30%. On the other hand, developing economies with a minimal industrial base have recycling rates close to 0%. (Woldemar, 2019) Are there any environmental justice issues related to your topic? (for example access to clean water, loss of land, etc) 1. ? source: (Woldemar, 2019), (EPA, 2024) V. Potential Solutions A. Environment: “Plastic can take anywhere from 20 to 500 years to decompose” (United Nations, 2021). That’s way too long to have plastic pollution cluttering the planet. A possible solution would be to perfect the production of biodegradable plastics that would break down within months instead of years. Economics: To keep containers inexpensive so prices don’t rise for the consumer. I would employ more recycling. Allow the consumer to turn in the container their product came in for a reimbursement. This would keep costs down for the consumer. Additionally, society needs to perfect recycling. Most “consumers do not know what can and can't be recycled, so they throw everything away or miscategorize recyclable materials.” (Huun, 2022). This leads to increased expenses at the recycling plant. Social/Human: Society needs to change their mindset about convenience items. If we raise the new generations from the beginning, that items are to be reused, not thrown away, the future generations will just see reusing items as a normal process. The EPA has proposed a plan to “Develop and make available a set of common recycling messages on nationally-significant issues (e.g. plastic film/bags), and increase awareness on how to recycle correctly”. (EPA, 2025) Propose a solution that would improve each of the pillars (so three solutions) 1. ? source: (United Nations, 2021), (Huun, 2022), (EPA, 2025) VI. Conclusion A. Perfecting recycling would be the best solution to our one use plastic problem. The EPA has committed to developing “a holistic, modern and adaptable national recycling infrastructure that embraces innovation and is resilient to changes in material streams” (EPA, 2025) Our local recycling service, Waste Management, has said on their website that they are also investing in their infrastructure at their recycling plant in an effort to better the efficiency of their equipment. Improving upon current recycling methods will make a positive impact on our planet’s future. Identify which solution is the most feasible and explain why 1. ? source: (EPA, 2025), (Woldemar, 2019) B. Humanity will rise to the occasion and improve upon their abuse of one-use plastics. I believe future generations will become more conscious of the misuse of plastics and work to improve upon its presence on our planet. Many agencies like the EPA, United Nations, and National Oceanic and Atmospheric Administration are using their effort to improve recycling education, increase processing efficiency, improve markets, and create global collaboration to end one-use-plastic pollution. (EPA, 2025) Make a projection about your issue and how it will change or stay the same into the future. 1. ? source: (United Nations, 2022), (EPA, 2025) Resource List: 1. Stuart, B. (2019, June).

UNFORMATTED ATTACHMENT PREVIEW 1 Biodiversity and Conservation Challenges in the Temperate Forest Biome Kawanna C Bullock BIO 122 April 19, 2025 Professor - Carlene Holt-Gray 2 Biodiversity and Conservation Challenges in the Temperate Forest Biome The temperate forest biome with a moderate and seasonal climate is located in many parts of North America, Europe, and Asia. Thus, this biome contributes mainly to the support of so many species of flora and fauna in the world and fulfills its part of the Earth's ecological system. Many ecosystems within this biome exist with specific species characteristics and their relations to their surroundings. Keystone Species: North American Beaver (Castor canadensis) Widely known as having the North American beaver as a keystone species of temperate forests. Dams that beavers build result in wetlands that provide an environment suitable for breeding grounds of several species of amphibians, fish, and birds. They equally play the roles of bio magnification, water purification, and control of floods. The changes in water flow and environment that beavers bring allow them to have wide-ranging effects on their habitats, which are expressed when a species fits into the keystone role. Invasive Species: Emerald Ash Borer (Agrilus planipennis) The shrub is currently an invasive species in the United States, and it came from Asia to the North American temperate zone. EAB was first identified in 2002 and has been known to cause the death of ash trees, effectively making it negatively impact socially, economically, and ecologically. Also, its effect is to bring about a change in species composition of the forest, reduced species diversity, and a change in the nutritional cycling patterns. Additionally, it has been found that attacks by EAB lead to the invasion of other invasive plant species, resulting from ecological disruption (Gougherty et al., 2023). In addressing the problem of EAB, biological control has been deployed, and parasitoid wasps, including Tetrastichus planipennisi and Spathius galinae, have been involved. These natural predators feed on the EAB larvae, hence aiding in controlling this 3 species to aid ash tree regeneration (Duan et al., 2023). Also, surveillance and isolation strategies are utilized to avoid the expansion of EAB to other regions that have not been affected. Carolina Northern Flying Squirrel (Glaucomys sabrinus coloratus) vs. Endangered One of the endangered mammals living in the temperate forest biome is the Carolina northern flying squirrel that dwells within the Mountainous regions of the Appalachian area. These include logging activities, climatic changes, and competition with other more aggressive animals, such as the southern flying squirrel. Most conservation efforts aim to rehabilitate areas such as high-elevation spruce-fir forests and monitor and count the population to help manage it. These measures aim to make the numbers of this tree-dwelling marsupial species more stable and increase their numbers in the future. Conclusion There are various threats to the temperate forest biome; the threats include the invasive species that threaten the everyday existence of the biome, and the decline of wildlife also threatens the biome. For the preservation of keystone species like the North American beaver, the roles must be identified, for the threats by invasive organisms like the emerald ash borer, they should be combated, and for the potentially endangered species like the Carolina northern flying squirrel, the preservation measures ought to be taken. More research must be done, education must be conducted for the public and management strategies must be implemented to strengthen the possibility of the temperate forest biome. 4 References Duan, J.

EAB was first identified in 2002 and has been known to cause the death of ash trees, effectively making it negatively impact socially, economically, and ecologically. Also, its effect is to bring about a change in species composition of the forest, reduced species diversity, and a change in the nutritional cycling patterns. Additionally, it has been found that attacks by EAB lead to the invasion of other invasive plant species, resulting from ecological disruption (Gougherty et al., 2023). In addressing the problem of EAB, biological control has been deployed, and parasitoid wasps, including Tetrastichus planipennisi and Spathius galinae, have been involved. These natural predators feed on the EAB larvae, hence aiding in controlling this 3 species to aid ash tree regeneration (Duan et al., 2023). Also, surveillance and isolation strategies are utilized to avoid the expansion of EAB to other regions that have not been affected. Carolina Northern Flying Squirrel (Glaucomys sabrinus coloratus) vs. Endangered One of the endangered mammals living in the temperate forest biome is the Carolina northern flying squirrel that dwells within the Mountainous regions of the Appalachian area. These include logging activities, climatic changes, and competition with other more aggressive animals, such as the southern flying squirrel. Most conservation efforts aim to rehabilitate areas such as high-elevation spruce-fir forests and monitor and count the population to help manage it. These measures aim to make the numbers of this tree-dwelling marsupial species more stable and increase their numbers in the future. Conclusion There are various threats to the temperate forest biome; the threats include the invasive species that threaten the everyday existence of the biome, and the decline of wildlife also threatens the biome. For the preservation of keystone species like the North American beaver, the roles must be identified, for the threats by invasive organisms like the emerald ash borer, they should be combated, and for the potentially endangered species like the Carolina northern flying squirrel, the preservation measures ought to be taken. More research must be done, education must be conducted for the public and management strategies must be implemented to strengthen the possibility of the temperate forest biome. 4 References Duan, J.
