One day , an unexpected things happens: Lightning flashes and thunder rumbles. It suddenly turned dark like the night in the morning. The world can not distinguish day and night. People are very surprised. Is it the world at the end of the day? The animals are too crazy to run. People are so scared, Some people stay at home to pray, others rush into the supermarket to rob everything they can.
It has been getting colder time by time. Poor people are staying at home and do not know what will happen tomorrow, such as waiting for the death. There is nothing but darkness and silence . Do not know how long it past away. Suddenly it turns bright! People running out from home and looking at the blue sky. What a familiar feeling like usual! People are as cheerful as they can. In the meanwhile the temperature gradually increased. Animals are clam down, and the plants are animated. Everything is all right.
What the hell is going on here? People are always afraid of the future, the doomsday. In 50 years ago, some scientists predicted that we can be anything but optimistic about our species’ future if we continue to degrade the environment. Due to the environment pollution, the loss of resources and other kinds of reasons, the end of the world really happened, the blue sky will leave us forever. After scientists' efforts, crisis disappear. At this time People realize the significance of protecting environment!Without the consumption of natural resources, the forest is more green, the river is more clear, the sky is more blue, the earth is more beautiful, and everything is so beautiful. The students singing and dancing in the playground, I can not help to smile. Then I heard a familiar voice: "My son ,get up to go to school" , I opened my eyes it was only a dream.
Looking out of the window, I think if human want to survive on the earth for a long time, we need to take care of the environment, conservation of resources. The earth is our home and we have the duty to take care of it for ourselves and for our later generations.Fortunately,more and more people have realized these problems.Measures have been taken to cope with these problems by the government.Laws have been passed to stop pollution.I hope the problem will be solved in the near future and our home will become better and better
