The atomsphere protect us from the Sun’s heat by reflecting a lot of the heat back into space. But, some gases in the atmosphere trap some of this heat, keeping the Earth warm even at night. This process is referred as the Greenhouse Effect and the gases that cuase it are known as greenhouse gases. These gases include water vapour, carbon dioxide, and CFCs. Humans are adding carbon dioxided and CFCs to the atmosphere all the time. Too much heat is being trapped, and the Earth is getting warmer. Global warming is leading to the melting of glaciers and polar ice caps and an alarming rise in sea levels. It will change the earth as we know it.
For over 20 years, Scientist have noticed an expanding hole in the ozone layer above each of the poles. This is due to the increasing use of chemicals that go into our refrigerators and aerosol cans. The hole means we have less protection from the ultraviolet rays of the Sun. these harmful rays can cause skin cancer.
