Conclusion
Why are rainforests destroyed?
Rainforests around the world are being
destroyed because governments, multi
national logging companies and land owners
want to use the trees to make wood for
timber, the land for farming, pulp for making
paper and road construction. Some poor
farmers have to use rainforest land because
they have nowhere else to live.
How are rainforests destroyed?
Rainforests can be destroyed in many different
ways. Here are a few:
Which species are harmed?
Experts say that we are losing around 137
animals, plants and insects species a day and
nearly 50,000 every year because of rainforest
destruction! When the rainforests are
destroyed lots of birds, insects and animals
loose there homes and feeding grounds
because they can’t survive without the trees.
For example a century ago there were 100,000
tigers in the world now there are less than
3000.
Effects on the eco-system
When the trees are destroyed there is less
oxygen in the world. If trees are cut down and
not replaced there is nothing to keep the top
soil in place. In the rainforest where it rains a
lot the top soil will be washed away, with no
top soil left new trees and plants can’t root
properly so they won’t grow. Therefore there
won’t be any food for animals and humans.
Current Statistics
Conclusion
In conclusion unless drastic action is taken the
last remaining rainforests in the world will be
consumed in 40 years. We are losing Earths
greatest treasures just as we are beginning to
realise their true value. We must act right now
or the rainforests and the species they
support will be gone forever!
