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)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!

One terribly cold day, a snowstorm hit our area. Needing firewood, I quickly set out with my best friend, Bruce, to look for a tree to cut down. Cutting down a tree in a snowstorm can be dangerous. (1) So to have a friend who could warn me of dangerso was important.
When I chose a big 23-meter-tall tree and prepared to cut it down, Bruce suddenly warned me, “Don’t cut down that tree! It’s too close to the power line!” I wasn’t sure about it. So I decided to disregard his warning. I couldn’t wait to finish the job and go back home. I began cutting down the tree. (2) When the tree fell, there was no longer any doubt whether my friend was right.
The tree caught the power line, bringing it to the ground. I considered cutting the tree off the line. After all, electricity can’t travel through wood. As I reached out my finger to touch the tree, pain ran up my arm and through my head. I had been shocked!
After I returned home and told my mother what happened, she quickly called the power company. Workers from the power company soon arrived. One of them asked if I had touched the tree, and when I told him I had, his face turned pale. “You should have been killed,” he said. It was my boots that saved my life.
(3)Within two hours, the workers removed the tree. Soon the snowstorm calmed down——but not my mother. Even though she was glad that I wasn’t hurt, my mother was still serious with me. After all（毕竟）, I shouldn’t have brushed off my friend’s warning.

People often say that the earth is like our mother. She gives life to all the living things on the earth and provides us with air, food, water and other essential things we need for living.
Once she was beautiful and rich, but now she becomes dirtier and dirtier, poorer and poorer. It is due to what we have done to her. Please have a good look at her: polluted rivers and lakes, growing deserts, the destruction of the forests and wild life, and the depletion (消耗，用尽) of the ozone layer (臭氧层)...
Can she bear to see her children putting the waste here and there? Can she bear to see her children cutting down the trees and destroying the grassland, to see the acid rain destroying everything? Can we bear to see our mother suffering (受苦) so much? Isn’t it time for us to ask ourselves whether this is the way to treat our mother?
Floods, droughts, acid rain..., these are the punishments (惩罚) from nature. Everyone should know that there is only one earth. If we go on treating her like this, it won’t be fit for us to live in any longer. It’s time for us to love her, take good care of her and cure her. We should save the earth so as to save ourselves.
