1. Deforestation &
Sustainability
Aya Hackett

2. What is deforestation????
 Cutting down, burning, and destroying forests
 It is practiced to make way for cattle raising and
agriculture, especially in the tropical rainforests of
South American and Southeast Asia, but also in
parts of western Europe and North America
 It is occurring at a rapid pace and if it continues,
rain forests will disappear by the year 2100 and this
would include more than half of the animal and
plant species on the planet

3. The importance of trees
 They absorb the gas from the air and
then replenish the air with oxygen
 More trees means better air
 They help perpetuate the water cycle
by returning water vapor into the
atmosphere
 Forests help prevent an increase in
global warming by serving as carbon
sinks---areas that trap and store
carbon dioxide
 Help to protect coastal regions,
control avalanches and
desertification, stabilize sand dunes,
and prevent soil erosion and
degradation

4. Negative Effects
 Loss of habitat for millions of species
 70% of Earth’s land animals and plants live in the
forests and they can not survive if they’re homes are
destroyed
 Climate changes
 Threatens the existence of every living thing on the
planet

6. What is this
doing to our
world?
•Nearly 40 million acres of
natural rain forests were
destroyed per year during the
1990s
•From 1990-1995, twice the
size of Italy had vanished
•70% of Earth’s land animals
and plants live in forests, and
many can’t survive if their
homes are destroyed

7. Home to many animals…

8. What are the reasons
behind these actions?

9. This happens because…
 Most of the reasons relate to money or peoples needs to
provide for their families
 Agriculture
 Practice of farming
 Growing crops
 To make areas of residence or industry
 Logging operations
 Provide wood and paper products
 Non intentional
 Wildfires
 Subsequent overgrazing

10. LETS MAKE A CHANGE!!

11. Taking Action!
•Reforestation
•Recycling items such as
books, toilet paper, shopping
bags
•Farmers rotate crops
•Cut mature trees & don’t cut
the baby trees
•Instead of firewood use coals
to heat up fireplaces

12. Making a Difference.
