change.

warmed the planet an average of 1.1 degrees & temperature rise range 1.5
degrees scientists believe that in 2050 life is not exits in the earth.

 Deforestation
 Green house effect

6. OZONE DEPLETION
Main reason:
 Chlorofluorocarbons
(CFCs)
 Pollution
 Unregulated Launches of
Rockets

7. DEFORESTATION
 The loss of trees and other vegetation can
cause climate change, desertification, soil erosion,
fewer crops, flooding, increased greenhouse gases in
the atmosphere, and a host of problems for
Indigenous people.

8. GREEN HOUSE EFFECT
 The greenhouse effect is the way in
which heat is trapped close to Earth's
surface by “greenhouse gases.” These
heat-trapping gases can be thought of
as a blanket wrapped around Earth,
keeping the planet toastier than it
would be without them
