All the world warmer The cause of global warming is the greenhouse effect
The causes of the greenhouse effect are: that people always go by cars instead of going by bike Factories Cows fart
The Arctic is melting and there will be less places for the polarbear to live
We should do: Use bikes instead of cars By bio food Recycle Buy things by natural materials Use electricity saving bulbs We should not do: Cut down forests throwing rubbish on the ground
We release too much CO2 We cut down the rainforest the trees exchange the CO2 into oxygen
