In fruits, vegetables, crops, flowers, grass, fields and rivers ... water is everywhere and never stops. A person who doesn't drink water for three days will die. This shows the importance of water. At present, the fresh water on the earth only accounts for 3% of the earth's water resources, of which only 0.5% can be directly drunk, and most of the fresh water on the earth has been polluted. Therefore, protecting water resources is an urgent task for mankind. Students, act quickly! Seeing the water flowing from the faucet rushing, I stepped forward and twisted it by hand; When walking along the river, don't throw your garbage into the river; Don't waste the water for washing clothes, use it to flush the toilet, and try to "use one water for multiple purposes" ... I believe that through our efforts, we will turn a deserted desert into a lovely oasis; Will make the grass fatter and the trees greener; Will make the water in the river jump happily, and the water in the river will jump happily. ...
By the way, the forest area is also decreasing. The global forest area is decreasing by about 1 654,380+00000 hectares every year. The reduction of forest area is an important reason for the expansion of desert area. The reduction of forests makes the climate worse, the rainfall decreases and the drought becomes more and more serious. The destruction of grassland and cultivated land makes one third of the earth face a serious threat of desertification. All kinds of harmful gases are discharged into the sky, wrapping our beautiful earth, resulting in the loss of polar ozone layer by 20% to 30% and Antarctic ozone layer by more than 50%. Without the protection of the ozone layer, the ultraviolet rays of the sun will invade and endanger human health. Let's talk about penguins in the Antarctic! As we all know, Antarctica is a relatively cold place, where many lovely penguins live. However, because tourists don't care about the environment and litter everywhere, the ecological environment in Antarctica has been incredibly destroyed. All kinds of penguins living carefree in Antarctica are also threatened by their lives. Due to human carelessness and uncontrolled destruction, only one lovely penguin in Antarctica is facing extinction. Yes! Humans savagely destroy the natural environment and cut down forests, resulting in a decreasing living environment for wild animals, and many wild animals are homeless. According to the statistics of IUCN, 1 10 species of mammals, 139 species of birds and 1000 species of vertebrates are endangered, and about 25,000 species of plants are endangered.
