保护环境英语作文 篇1
There are many diseases that are harmful to human health and even threaten human life. Human into the 21st century, the world has occurred in the number of amazing changes. In the people for the rapid development of science and technology, but also experienced a better anxiety and even disaster. In addition to the panic of the development of high-tech, especially biotechnology, war and disease seem to bring mankind directly to the door of hell.
Water pollution on the human body harm, the body in the process of metabolism, with drinking water and food, the water of various elements through the digestive tract into the various parts of the body. When the lack of water in some of the human life process necessary elements, will affect human health. For example, in some areas of water iodine deficiency, long-term consumption of this water, it will lead to "big neck disease", is the medicine called "endemic goiter." When the water contains harmful substances, the greater harm to the human body. Carcinogenic substances can be consumed by eating contaminated food (food, vegetables, fish, etc.), into the human body, but also through the water into the human body. According to the survey, drinking contaminated water, suffering from liver cancer and gastric cancer and other cancer incidence, than drinking clean water is about 61,5% higher. When the sewage contains mercury, cadmium and other elements into rivers and lakes, the aquatic plants put mercury, cadmium and other elements to absorb and enrich them, fish eat aquatic plants, and in its body to further enrichment, people eat poisonous Fish, mercury, cadmium and other elements in the human body enrichment, so that the human body and death. In this way, from the aquatic plants → aquatic small animals → small fish → big fish → the body, forming a food chain. The body eventually became mercury, cadmium and other elements of the "foothold."
Water pollution hazards to aquatic organisms Water lives in a variety of aquatic animals and plants. Biological and water, between biological and biological complex material and energy exchange, from the number to maintain a dynamic balance. But under the influence of human activities, this balance has been destroyed. Some of the beneficial aquatic organisms are poisoned when humans release pollutants into the water, and some of the stained aquatic organisms will multiply, consume a lot of oxygen dissolved in the water, so that the beneficial aquatic life is forced to relocate due to hypoxia Or death. In particular, some toxic elements, both difficult to dissolve in water and easy accumulation in the body, causing great harm to humans. Such as mercury in the water content is very low, but the content of aquatic organisms is very high, the content in the fish is also surprisingly high. Assuming that the concentration of mercury in the water body is 1, the concentration of mercury in the aquatic organisms is about 700, and the concentration of mercury in the fish is as high as 860. Thus, when the water is contaminated, on the one hand led to biological and water, biological and biological balance between the damage, on the other hand some of the toxic substances continue to transfer and enrichment, and ultimately endanger human health and life.

We all know that if we do not protect the environment, the various resources on the planet will slowly dried up; if you do not protect the environment, people will face the demise; if you do not protect the environment, not only human beings, the Earth will gradually go to the demise! The earth we live in is so beautiful, so cute, and it is so easy to break. We often can see some of these lenses: a tall and mighty law enforcement officers walking, "Pooh" soon as a spit spit on a clean ground; a middle-aged man smoking For a moment put the cigarette butts that have not extinguished on the ground. I have seen such a picture: a father took the son of yogurt is taking a hurry to go, his son asked his father, where the bottle throw? Father said casually throw. Son said, the teacher said, 'can not just throw things! 'Father said impatiently, oops, special circumstances special treatment Well! Then, put the bottle at hand on the roadside. People often throw things, the trash in less than ten steps, they do not want to take a few steps, do not throw things into the trash. If everyone throws a junk, the earth will become a trash ocean.
There is also a lens, a mother to the children bought a popsicle, the tear off the paper easily thrown on the side. After the child saw it, picked it up and was ready to throw it into the trash can, but at that moment the mother hurried up and took off the paper on the child's hand and said, "The same is the earth citizen, why is there such a big contrast! If everyone picks up the trash around, how beautiful and clean our earth will be! Are those who destroy the environment to wait until the environment under their destruction "unsightly" before returning to continue to protect the environment?
Classmates, let us act up, pick up the feet of the garbage, thrown into the trash can not let the earth mother to reproduce the previous glory it! Let us work together to create a clean home.
