Major sources of pollution that are destroying the environment include air, plastic, water, and soil pollution. Air pollution is largely caused by burning fossil fuels for energy and transportation, releasing gases like sulfur dioxide and ozone. Plastic pollution has resulted in over 8 million tons of plastic ending up in oceans each year. Water pollution stems from industrial and municipal waste that contaminates waterways and harms marine life. Various sources like nutrients added to soil can pollute the soil and harm plant life and water sources.
