Extinction of species

1
Extinction of species
I need to react quickly ! ?

• Is not it important ?

2

• Many animals will be on the verge of extinction
  thats to say that many species disappear because
  they lose their home

3
The causes to explain the extinction of species

• There are different causes to explain the
  extinction of species
• First of all, the human activities, like the
  hunting, the fishing, are very bad for the
  animals because the human beings catch more and
  more fish, above all the japonese who catch the
  dolphins.
• Men hunt birds In the last 500 years, human
  activity has forced 844 species to extinction.
• Then, the climate change, for example the
  temperature of oceans rises more and more, so the
  fish arent used to the hot temperature and they
  die. And the animals which live in the savannah
  cant eat because there isnt vegetation anymore.
• Furthermore, the pollution, because the boats who
  are sinking, dump petrol in the sea, so fish and
  birds die.

4
Consequences

• Without insect, trees would give no fruit.
  Without birds, plants would reproduce very
  slowly.
• There will not be animals in zoo.
• The food chain will be broken.
• Human beings will become vegetarian.

5
The sOluTioNs

• To reduce the extinction of species, there are a
  lot of solutions but the men must take them
  seriously
• If we stop wasting paper, we will not need to cut
  a lot of trees so the houses of animal will not
  be destroyed.
• If we use less cars, boats etc, the environment
  will be less polluted and the animals will live.
• If we stop the deforestation, the animals will
  not die.
• If we fish more, there will not be fish.
• If the japonese continue to kill dolphins, the
  species will disappear.
• If we stop hunting elephants for ivory, they
  will not disappear.
