Environmental Issues 1) Land Pollution • Increasingly, humans are polluting the land with toxic and nuclear waste, solid waste, and pesticides. • In 1960, each U.S. citizen generated 2.7 pounds of garbage on average every day; by 1996, this figure increased to 4.3 pounds. The U.S. discards nearly 160 million tons of solid waste each year, enough to bury 2,700 football fields in a layer ten stories high. Some of this waste is converted into energy by incinerators, but more than half is taken to landfills. • In the U.S., about 500,000 tons of 600 different types of pesticides are used annually. Pesticides contaminate food, water, and air and can be absorbed through the skin, swallowed, or inhaled. 2) Water Pollution • Our water is being polluted by a number of harmful substances, including pesticides, industrial waste, acid rain, and oil spills. In 1993, there were more than 9,000 oil spills in and around U.S. waters alone, totaling more than 1.5 million gallons of spilled oil. • 500 million pounds of toxic waste are absorbed by our water supply each year.
