I think people should do more things online from home.  Why pollute the air by driving your car to the supermarket, when you can order your weekly shopping on the Internet—You can also book holidays as well.

I try to use public transportation whenever I can. I take the bus to college and walk home. When my mum wants to give me a lift, I always refuse, as I can get there quickly by bus. Also the buses in my town are electric so they are environmentally friendly!

Why not use two wheels? Any motorcycle will use less fuel (燃料)than an a car. You don’t get caught in traffic jams either. But in my opinion, the best thing is a bicycle. They don't produce any pollution and help you to keep fit at the same time.

I can’t get to my university by bus or train. So I found three other girls who live nearby to have a car share with. And now we take it in turns to drive every day. I have cut down the costs —and most importantly, —I am helping the environment!
