2分钟英语演讲稿范文:Blue Planet
our environment is being polluted faster than nature and man's present efforts can prevent. time is bringing us more people, and more people will bring us more industry. so many trees will be cut down, and more large cities will be set up. lots of waste material, in return, is produced and harms the environment. so some experts declare that the balance of nature is being upset, so that the very survival of man is in danger.
how can we solve this problem? the answer is that we must control the speed of growing people, forbid everyone to cut down trees and pour waste water into rivers and so on.
if we achieve this, the environment will turn very clean, and our future will be full of happiness.
