Boys and girls，
I'm honoured to give this speech. With the development of society and economy, the number of private cars is increasing at a surprising speed. As we all know, cars give off poisonous gas such as carbon dioxide, causing global warming, frequent natural disasters, diseases and so on. In order to protect our environment, it is high time that we should go green.
Firstly, we should raise people's awareness of the importance of going green. Secondly, using public transportation or riding bicycles instead of using cars can make a great difference to the problem. What's more, we should take full advantage of water, electricity, paper, food and so on. Last but not least, it is a good idea to classify rubbish and recycle it in our daily life.
That's all. Thank you.
