Deforestation

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
  worlds animals, plants, and microorganisms will
  be destroyed or endangered due to deforestation.

Rate of Deforestation in the Tropics
.                                

• As shown in the chart on the right, the rate of
  deforestation has grossly increased from 1960-
  1990. It has also increased since this graph was
  made.

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.

The Truth

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

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 Environments 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 Earths
  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.

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.

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.

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.
