2. Temperature increase.
3. Fog.
4. Climate change.
5. Melting of glaciers.

The other effects of De-Forestation are:

1. Soil erosion destruction.
2. Water cycle.
3. Loss of biodiversity.
4. Climate of change.

Benefits of Trees and Forest on Earth:

1. It helps in sustain all life and living organisms on earth.

Advantages of planting trees in reducing global warming

1. An average size tree creates sufficient oxygen in one year to provide oxygen for a family of four.
2. Planting trees can cut air-conditioning/ electricity costs up to 50 percent.
3. Planting trees for the environment is good as they are renewable, biodegradable and recyclable. 
4. If we plant 20 million trees, the earth will get with 260 million more tons of oxygen.
5. Once acre of trees can remove up to 2.6 tons of Carbon Dioxide each year.
6. During photosynthesis, trees and other plants absorb carbon dioxide and give off oxygen.
7. Trees keep in cheek the air and water pollution.
