I remember a few years ago, mom and Dad took me to visit grandma, grandma in front of asmall river, the river clear, shining, slowly forward flow. The river, a group of aunt laugh in the laundry, a group of children are swimming in the river, play. My mother and I rolled up his trousers pebbles in the river fishing, father leisurely beside. This pleasant and peacefulscene, now I remember.
However, a few years after the day, when I see the river again, startled. The river had notclear, the water is turbid, mixed with some dirty, bare riverbed, water is quickly exhausted, but also exudes stench. These smelly water is flow out from where? I looked around, I saw a few factories to the skies injection with smoke, smog clouds, then turn into acid rain falling down,poisoning the earth; at the same time, the factory also continuously to the river waste water,the clear rivers into poison water turbidity. Coal is the nature of hundreds of millions of yearsis the solar energy, and a lot of development in a short period of several hundred years and use to generate large quantities of carbon dioxide, coal burning, causing the greenhouse effect on earth. At the same time, the number of sulfur dioxide gas in coal combustion generated a small amount of sulfur, with the rain falls to the ground, the formation of acid rain.Acid rain destroyed a large number of forest ecological system, become "air killer."
Drainage field water is continuously to the river discharge of sewage, and even the riverplants died. Is not this dump? The clean water is no longer clean, water no longer flows, the air is no longer fresh. The people what about this throughout the years of the old river holdwhat kind of attitude? Is to continue to pollute the environment or the protection of the river?The destroyer is do or do the greens?
Due to water pollution and groundwater overexploitation, human freshwater resources hasbegun an emergency. Due to deforestation and over reclamation, grazing, soil erosion and land desertification is becoming a serious problem. Due to the earth's destruction, as of 2000there have been 23000 species of plants and 1000 species of vertebrates extinction, noweach hour has 1 species disappear from the earth. Land pollution, humans cut down trees,rock fall, the flood destroyed houses, drowned crops into the river; people littering, causingwater pollution, everywhere discarded plastic bag, the formation of white pollution. People kill the animal, animal extinction caused by decapitation of flowers; the people, so that we have lost the beautiful. There is only one earth, we live on earth, we should protect the earth,protect our homeland.
In order to home, for ourselves, for the benefit of future generations, let us join hands, to protect the natural environment, the creation of new world with our efforts. We believe,tomorrow will be better!
Taking care of our environment is our duty.But how we can do to make our environment more beautiful? At first,we must make ourselves clean.For example,we must wash our clothes when they are dirty.We should not litter waste things about,and draw on the wall.We mustn＇t spit in public or cut down trees. We should plant more trees around our neighbourhood.We should pick the rubbish up and throw them into the dustbin when we see them. We must make our world more and more beautiful,don＇t you think so?
