2 Today's theme - Lesson 8: Polar Bears and Global warming. picture

In the spring of 2008, the polar bear was called an endangered species. This law says "an endangered species is an animal that is in danger of becoming extinct in the place it normally lives."

The polar bear is the first animal that has been called "endangered" as a result of global warming. Global warming is caused by CO2 and other greenhouse gases that become trapped in the atmosphere. Heating homes, driving cars, and burning rubbish all need fossil fuels that lead to global warming.

Polar bears live mainly on the sea ice in the Arctic. This is where they hunt for fish and build up fat reserves. When the ice melts many polar bears move to land and live off their fat. In the Arctic, global warming is causing the ice to melt earlier, so the polars bears have less time to find food. If they have to swim too far they will drown from exhaustion and hunger. People say that 25% of the Arctic sea ice has disappeared in the past 30 years.

It is not just the polar bear that is at risk in the Arctic. Every species of plant, animal, and insect there is threatened by global warming. But it is useful to study the polar bear because it is at the top of the food chain. Also, people like to give money to charities that save large animals, and they are less interested in saving smaller animals or insects.

It is important that animals like the polar bear are put on the "endangered species" list. That means there are laws to stop people hunting them for food or sport. Also, agencies can receive money and other things to protect their habitat. Once a species is put on the list, it has a very good chance of surviving. If an endangered species is not put on the list, it is at great risk of becoming extinct.

3 Using "will" for spontaneous decisions

Watch this entertaining man talk about "will" and "going to"!

Stop the video at about 2 minutes 50 and write down the 5 situations he suggests where we use "will".

1 new decision
2 offers/ favours/ help
3 agreeing
4 refusing
5 promises

Let's try using "will" for giving help... say I'll...

I've got a terrible headache! I'll give you an aspirin
Oh no, I've dropped my papers everywhere! (help you pick them up)
My TV's not working! (fix it)
I'm starving! (make you something to eat)
I don't know how to make an omelette... (show you how to make one)
Oh dear, I've left my wallet at home! (pay the bill)
Oh no, we don't have enough butter to make the cake! (go and buy some)
I'm working late so I don't have time to pick up my mother from the airport (pick her up)
We have so many things to move, I don't know if I can do it all on my own! (help you move)
