Deforestation Deforestation is clearing Earth’s forests on a massive scale‚ often resulting in damage to the quality of the land. Forests still cover about 30 percent of the world’s land area‚ but large areas the size of Panama are lost each year.

Global warming Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane) trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. This hurts many people‚ animals‚ and plants. Many cannot take the change‚ so they die. The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This is like when heat
