Activity 3.3.3 – My Plastic Use

Image
Microplastics: Definition, Sources, and Impact Microplastics are small plastic particles that measure less than 5 millimeters in size. These tiny particles are created when larger plastic products degrade or break apart due to environmental factors like UV radiation, mechanical wear, and exposure to water. Microplastics can also be intentionally manufactured for use in personal care products such as exfoliating scrubs or toothpaste (Haab & Haab, n.d.). Despite their small size, microplastics have a significant impact on both the environment and human health. This essay will outline the definition of microplastics, their sources, how they enter the environment, and the consequences they pose to humans ecosystems. Where Microplastics Are Found Microplastics are found in a wide range of environments. Oceans are perhaps the most well-known repository for these particles, with the Great Pacific Garbage Patch being one of the largest accumulations of plastic debris in the world (...

Activity 3.3.1 Air Pollution Core Activity

Image
1. Air Pollution Basics Sulfur Pollutants Sulfur pollutants are primarily emitted through the combustion of fossil fuels, such as coal and oil, and can also be a result of volcanic eruptions. The combustion of sulfur-containing fuels releases sulfur dioxide (SO₂) into the atmosphere, which can have harmful effects on both human health and the environment. For example, sulfur dioxide is a key contributor to acid rain, which can damage ecosystems, soil, and aquatic habitats (Freedman, 2018). Nitrogen Pollutants Nitrogen pollutants include a variety of gases such as nitrogen oxides (NO and NO₂), nitrous oxide (N₂O), and ammonia (NH₃). These pollutants primarily originate from human activities like the combustion of fossil fuels in vehicles, power plants, and industrial processes. Nitrogen compounds contribute to the formation of ground-level ozone, which is a major air pollutant that can irritate the respiratory system and contribute to smog formation (Freedman, 2018). Hydrocarbon ...

Activity 3.2.3.1 Solar Power and Energy Policy

  1. Exploratory Probe basic facts and knowledge found in the reading. ( What research evidence supports _________? Type up several facts and basic knowledge from the reading. Relate this to what you see in other resources and prior activities for stronger scores.) ) In the NPR article How Solar Grew in Georgia Despite Lack of Mandates on Renewable Energy the authors Hsu and Kelly (2019) explain how Georgia became a leader in solar energy without having laws that require renewable energy. They explain that the growth came mainly from companies like Georgia Power, which decided to invest heavily in solar energy. These companies saw the benefits of solar power, including saving money and reducing their environmental impact. Georgia’s sunny climate and the availability of land made it a good place for large solar farms. Even though there were no strict rules forcing solar energy use, the article shows that the state’s solar growth was possible because of private sector investmen...
