Good environment can make people feel happy and fit . To improve the environment means to improve our life. 　　　　We should plant more trees and flowers around us . We shouldn’t cut them down . We should stop factories from pouring waste water into the river and waste gas into the air. 　　　　Whenever we see litter on the ground , we should pick it up and throw it into dusbins. Never spit in public. Don’t draw on public walls. It’s our duty to protect the environment. Trees can be damaged or killed by a wide variety of construction activities. Some practices lead to obvious injuries such as broken branches or torn bark. Open wounds of this type deplete a plants energy resources and provide entry points for insects, or for diseases such as oak wilt.The worst damage, however, often remains hidden underground. Roots are one of the most vital parts of a tree. They are responsible for nutrient and water uptake, store energy, and anchor the plant. Because they are so important, it is critical that you protect roots that lie in the path of construction.Trees are never the same shape below ground as they are above, so it is difficult to predict the length or location of their roots. Typically, however, approximately 90-95 percent of a trees root system is in the top three feet of soil, and more than half is in the top one foot. The part of this root system in which construction damage should be avoided is called the Protected Root Zone With the improvement of our living standard, more and more people can afford a car. As a result, our roads are more often than not crammed with cars. However, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. So nowadays we advocate to lead a low-carbon life. My suggestion is we should ride bikes more often instead of driving cars.By riding a bike, we can not only exercise our body but also protect our environment. Why not have a try, my dear friends? 与我们的生活水平的提高,越来越多的人都买得起汽车的。因此,道
