You will hear an interview between Adam Wilkins, a science teacher, and the Science Hour programme host, Jeremy Jenkins.0:04
And mark statements 47 to 50 as true, false or not stated.0:13
Adam, we keep hearing that humans are destroying the different habitats on Earth.0:23
Can you tell us what this actually means?0:28
Man has been damaging the land, sea and air around him, and as a result, he is also threatening the survival of plants and animals that live there.0:32
Why is this happening?0:41
One of the reasons is that we are increasing the world's population by about 1 1/2 billion people every 10 years.0:43
More people means we need more food and therefore more land to grow the food.0:51
So in trying to feed all these people, we destroy the habitats of the animals and plants that live in the areas we transform into farms.0:57
Experts believe that over 100 species become extinct every day because of us.1:06
What are some other causes of habitat destruction?1:12
Scientists believe that the poisonous chemicals we throw in the sea will cause the sea life to change or die out.1:15
Also, they say that we are destroying the forests which make half of the oxygen in the world.1:22
Of course, we cannot live without oxygen, but a large number of us seem to believe that this problem isn't so serious and hope that it will just go away by itself.1:28
So how can we stop destroying natural habitats?1:38
There are dozens of things we can do, but I believe that we should first turn our attention to our seas, lakes and rivers.1:42
People keep throwing rubbish and poisonous chemicals into them, putting wildlife at risk.1:51
And this is one of the most serious problems that a huge number of plant and animal species face.1:56
Well, you've given all of us much to think about.2:02
