Land pollution is pollution of the Earth’s natural land surface by industrial, commercial, domestic and agricultural activities. In an average day people throw out 200,000 tons of edible food and throw 1 million bushels of litter out their car windows. The main human contributor to land pollution are landfills, approximately half of our trash is disposed in landfills only 2% of our waste is recycled.
Air pollution is environmental contamination with man-made waste into the air. Every year 335,000 Americans die of lung cancer, which is a direct result of air pollution. The air we breathe is composed of a mixture of gases, 78% nitrogen, 21% oxygen, and a small percentage of other gases like argon, carbon dioxide, and water vapor. Vehicles exhaust contributes to 60% of carbon monoxide emissions in the U.S. and up to 95% in large cities.
Water pollution occurs when a body of water is affected due to the addition of large amounts of chemical and physical matter. Over 73 different kinds of pesticides have been found in the groundwater that we eventually use to drink. Over 1.1 billion people in the world lack access to clean water. Every year in the U.S. 1.2 trillion gallons of sewage and industrial wastes are discharged into their waters

To help prevent land pollution. Reuse as many items that we can, buy biodegradable products, store all liquid chemicals and waste in spill-proof containers, eat organic foods that are grown without pesticides, use a drip tray to collect engine oil, don’t dump motor oil on the ground.
