5. AIR POLLUTION Heating systems, car exhaust fumes, and the burning of oil, gas or coal create too high a concentration of CO₂ (carbon dioxide) in the air. This gaps traps too much heat on the ground and the earth becomes hotter.

6. THE PRECIOUS LAYER The layer of the atmosphere which protects the earth against ultraviolet radiation has been permanently damaged by CFC gases ( chlorofluorocarbons). These were used in aerosol sprays and refrigerators until 1995.

7. THE LIST OF THE NEGATIVE EFFECTS OF THE ENVIRONMENTAL PROBLEMS Health problems, skin cancer, destruction of plants and animal species, global warming, uncontrolled growth of algae, ice melting and sea level rising. SAVE OUR EARTH!!!!!
