Sarah’s report gives us some reasons to be optimistic

and some reasons to really worry. Sarah.

Sarah: Hello there. Yes, it’s true that climatic change

does affect animal and plant life but not always to

the point of disaster. Many animals and plants are

actually very adaptable – you know, able to change

according to conditions. Of course, historically ice

ages and droughts – a severe lack of water – have

completely destroyed certain types of animal and

plant life, but many managed to survive extreme,

long-term climate change by adapting.

Now, many biologists and ecologists believe the Earth

today may again be in the middle of climate change

because over the last century many studies have

shown rising global temperatures, on average about

half a degree centigrade, and although this may seem

very little, it is actually happening much faster than

before and it can affect life enormously.
