ANIMALS IN DANGER OF EXTINCTION
Hello, today I'm going to explain you about my social topic I have chosen: Animals in danger of extinction.
At first I'm going to tell you the causes why so many species are in extinction, and then I'm going to show you some examples of the most in danger animals.
There are two big groups to differentiate: One is natural causes and the other is human causes.
Natural causes
● Climatic Heating and Cooling: Climate Change is caused by a number of things. The effect that climate has on extinction is very big. When the weather changes very fast and very strong, and the difference of temperature is very big, some species of animals don't have a chance to survive. Because when it's very cold the food for them is freezing and when it's to hot, normally there is no water.
● Acid rain: Another naural cause is the acid rain. The problem is when this rain falls on the earth, it increases the acidity and it affects on plant life. And when the animals eat the plants they become ill and die.
● Diseases: The last problem is that each species has defense mechanisms like immunities and the ability to fight diseases. But with the changing climate some spacies are losing their ability and become ill.
Human causes
● Climate change: The humans are the most responsible of the climate changing, so we are the responsibles of some natural causes I have said before.
● Destruction of habitat: There is another problem, the humans are building new citys everywhere, and for that they have to destroy a lot of woods where a lot of animals live. So a lot of them where dead or died because they had no food.
● Pollution: And the last problem is pollution. Pollution is the introducction of toxic gas in the space. The most responsibles for that are the factories because they don't control too much what gases they leave in the space. Another tipes of pollution are fire, farming and building of citys.
Examples of animals in danger
Now I'm going to show you some of the animals that are in danger of extintion.
● Siberian Tiger: It's a tipe of tiger which lives in Siberia. It's a very big animal and it could arrive to dispite more that 300 kilos. They are white and black and now only exists 200 of this specie in the world.
● Giant otter: Has disappeared in Uruguay and only a few left in Argentina.
● Iberian imperial Eagle: There are only 150 pairs left free.
● Sea turtle: Chased by collectors and offered in luxury restaurants.
● Scarlet Macaw: Imported in large quantities to the USA.
● African Black Rhinoceros: There are only 2.000 left. During the 1970s there were more than 65.000.
● Giant Panda: They were used by Zoos and wanted for their skin. There are only 1.000 left in the World.
So, in conclusion, in my opinion I think that it's a very big problem because in maybe 100 years, a lot of spacies will have disappeared from the world only because the humans don't care about it. And I hope that in the future we will give more importance to this problem.
So, my presentation finishes here, have you any questions?
