Hello, I will present an exhibit on biodiversity
biodiversity is left of nature's beauty
but is threatened by man.
The man started the sixth mass extinction of species, the last took place years ago 65million.
The causes are:
Pollution :
animals consume toxic products we throw away. For example, fish are eaten by seals which in turn
are eaten by polar bears: all these animals are so intoxicated.
Another example: 1.5 million animals are killed because of plastic waste by 4000 days.
The destruction of the territories:
For example, carbon dioxide releases have a strong impact on the glaciers, the melting of these changes the environment in which live
some species, which puts them at risk: for example, its causes significant effects on polar bears, because they must
often use frozen expanses on which they live to hunt.
Fishing and hunting:
The massive fishing of species in threat of extinction past but also their predators:
For example because of the sin, 90% of whales were destroyed in 100 years
They are hunted in Japan, Denmark and Norway
Because of hunting for their fur, tigers are endangered
Result :
Every 20 minutes, a species disappears .Many species are endangered and many have already disappeared.
For example clouded leopard from Taiwan who disappeared in 2013 and the African black rhino west who disappeared in 2011
solutions:
To prevent the loss of species, zoos are created for certain endangered species are under protection and reproduce.
In our daily life, you must:
do not throw trash in nature because it poisons the land
fight against global warming
