emission sources

Emission sources are the origins of pollutants released into the air, water, or land. They include both natural sources, like wildfires and volcanic eruptions, and human activities, such as burning fossil fuels for electricity and transportation, industrial processes, agriculture, and waste disposal. These sources release particles, chemicals, and gases that can impact environmental and human health. Understanding where emissions originate helps in developing strategies to reduce pollution, improve air quality, and address environmental challenges effectively.
