Earth Hour
Earth Hour is held toward the end of March each year. During Earth Hour, people all across the world switch off the lights they do not need. They do this to show their awareness of climate change.
The first Earth Hour was held in 1977 in Sydney, where more than 2.2 million people switched off their lights. Today, more and more cities are taking part in the event, such as Beijing, London, Rome and New York, and landmarks like the Empire State Building and the Golden Gate Bridge will go dark.
● Choose a subject that you care about the most. It could be water pollution, air pollution, etc.
● Find out more information about your subject. Look it up on a website or in a book.
Work in groups. Decide what type of pollution you want to talk about.

Discuss your subject.
● Take turns to say what you think about the problem and what can be done.
● Listen to what others say. If you agree with what they have said, say “I agree”, “That’s
true” or “That’s a good point”; if you do not agree with what someone says, say “I’m
sorry, but I don’t agree. I think that…”
I agree with you that air pollution is one of the most heavy problems. Tons of energy is needed to run the factories of modern industrial nations. Cars, trains, planes need energy, too. Nearly all of this energy is produced by burning fuels. It produces waste, the waste remains in the air, causing air pollution. The government has took steps to reduce air pollution, as students we can do little things to help such as riding bikes to school instead of taking private cars.
Present your group’s ideas to the whole class.
