1. Deforestation A Main Cause of Global Warming
By Miles Weinberger, Jonathan Arganek, Carter Russell, and Connor Stephens.

2. The Facts
Rainforests once covered 14% of the Earth, and now only cover 6%.
One and a half acres of rainforest are lost every second.
Over the next 25 years, almost half of the world’s animals, plants, and microorganisms will be destroyed or endangered due to deforestation.

3. Rate of Deforestation in the Tropics.
                               
As shown in the chart on the right, the rate of deforestation has grossly increased from It has also increased since this graph was made.

4. More Facts 80,000 acres of rainforest are destroyed everyday.
Experts estimate that we are losing 137 plants, animals, and insects every single day to rainforest deforestation.
If we are losing 137 species a day, then that is about 50,000 a year.

5. The Truth 80,000 acres of rainforest are destroyed everyday.
Currently 121 prescription drugs sold worldwide come from plant derived sources.

8. Reasons: The Human Side of Deforestation
Humans cut down trees and bushes to create farmland and space for building homes.
And also to obtain wood from the trees that are cut down.

9. Los Pineros
The men who work in the pines are a major source of manual labor in the American pine industry.
They are underpaid and often work in bad conditions.
They plant plants that stunt the growth of commercial pines.

10. Soil Erosion
Soil erosion occurs from man-made action such as overgrazing or unsuitable cultivation practices.

11. The Reasons: The Environment’s Side
Cutting down trees takes away habitats for animals all over the world.
Plants are what takes Carbon Dioxide out of the air and replaces it with oxygen.
This is important because Carbon Dioxide is a greenhouse gas that traps heat in the Earth’s atmosphere and warms the world.

12. Soil Erosion
Acts such as overgrazing leave the land unprotected and vulnerable.
When strong winds or rainfall occur soil made be detached, transported and deposited in the form of mudslides.
The worst effect of deforestation is soil erosion.

14. Mudslides
As shown in the previous slide, mudslides are a horrible and atrocious effect of deforestation.
Mudslides are caused when trees are cut down then there is nothing to hold the soil in place.

15. Green Wall of China
The Green Wall of China will be a wall made out of human-planted forest strips that will block the Gobi Desert.
The Green Wall of China is supposed to be 2,800 miles long and to be finished in 2074.

17. Solutions for Deforestation
There are many different solutions that Americans are taking to alleviate the effects of deforestation.

18. Recycling Paper
Recycling is reusing trees that have already been made into paper.
Recycling paper instead of making it from new material generates 74 percent less air pollution and uses 50 percent less water.

20. Encourage people to live in a way that doesn't hurt the environment.
TREES
Teach others about the importance of the environment and how they can help save rainforests.
Restore damaged ecosystems by planting trees on land where forests have been cut down.
Encourage people to live in a way that doesn't hurt the environment.
Establish parks to protect rainforests and wildlife.
Support companies that operate in ways that minimize damage to the environment.
