The document discusses several environmental issues including global warming, air pollution, ozone layer depletion, deforestation, heavy traffic, acid rain, water pollution, waste disposal, and noise pollution. Global warming is caused by increased greenhouse gases around the earth and causes rising world temperatures. Air pollution makes breathing difficult in cities due to gases, car fumes, and smoke. The ozone layer is being damaged, which is dangerous as it prevents harmful solar radiation. Deforestation involves cutting down or burning all the trees in an area, reducing habitats for wildlife and oxygen. Heavy traffic causes problems like air pollution, stress, and noise pollution in cities. Acid rain contains harmful acids from emissions and dissolves in clouds. Water pollution
