Oysters are highly effective at filtering water due to their ability to pump large volumes of water through their gills, where they extract plankton and other nutrients. A single oyster can filter up to 50 gallons of water per day, removing pollutants, sediments, and excess nutrients. Their natural filtration process helps maintain water clarity and quality, promoting healthier marine ecosystems. Additionally, their filtering activity can reduce harmful algal blooms, contributing to overall aquatic health.

Outdoor air pollution is influenced by several factors, including industrial emissions, vehicular exhaust, and the burning of fossil fuels. Weather conditions, such as temperature inversions and wind patterns, can exacerbate pollution levels by trapping pollutants close to the ground. Additionally, urbanization and population density lead to increased energy consumption and waste generation, further contributing to air quality degradation. Natural events like wildfires and dust storms can also introduce significant amounts of particulate matter into the atmosphere.

Microscopic particles of ash or dust in the air that can cause health problems are called particulate matter (PM). These particles vary in size, with PM2.5 and PM10 being the most commonly referenced, indicating particles that are 2.5 micrometers and 10 micrometers in diameter, respectively. Exposure to high levels of particulate matter can lead to respiratory issues, cardiovascular diseases, and other health complications.

Waste materials can be handled through processes such as recycling, composting, and waste-to-energy conversion to reduce pollution. Recycling helps to repurpose materials, minimizing the need for new resource extraction and reducing landfill waste. Composting organic waste transforms it into nutrient-rich soil, preventing methane emissions from landfills. Additionally, waste-to-energy technologies can convert non-recyclable waste into electricity or heat, further reducing environmental impact before disposal.

In Pennsylvania, the fine for littering can vary depending on the amount and type of litter. Generally, the fine for littering is at least $300 for the first offense, and it can increase significantly for subsequent offenses or for larger quantities of litter. Additionally, offenders may also be required to perform community service or attend littering education programs.

As of recent assessments, the Yamuna River is heavily polluted; approximately 70-80% of its water is considered unfit for drinking or bathing.
