5th June: Environment Day

Today we are working on different environmental problems:

• If people don´t protect animals, they become extinct .
• If people cut down trees, it is deforestation.
• If you use air-conditioning intelligently, you save up energy .
• If icebergs melt, the sea level rises.
• If you burn oil, it produces greenhouse gases .
• If factories use fossil fuels, the greenhouse effect gets worse.
