保護環(huán)境英語作文 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.

One possible version:
The problem of “white pollution” caused by used plastic is becoming increasingly serious, in which plastic shopping bags play an important role. In China about three billion plastic shopping bags are consumed every day, which results in a great waste of resources and heavy environmental pollution. Luckily, The government has put a nationwide ban on the use of free plastic bags, demanding that all stores and supermarkets not provide customers with free plastic bags after June 1. The rule will undoubtedly reduce the use of plastic bags and enhance the awareness of environmental protection. It is highly advocated that we should turn to cloth bags and shopping baskets from now on.

Developing Economy or Protecting Environment?
Some people hold that we should put developing the cconomy in the first place.Only by further balancing and developing our economy can we get rid of poverty and gain the overall development of the coun-try.Otherwise,many people,espccially in rural areas,may live in pov-erty and their children may drop out of school because they could not af-ford compulsory education.
On the other hand,many people insist that environmental protec-tion should be a top priority.They hold that it is the rapid and unrestrict-ed development of economy that leads to the present situation in which most parts of the world are polluted.If the problem is left unsolved,someday we may not survive on this planet,let alone develop our econ-omy.
In my opinion,both economy and environmental protection are our urgent tasks at hand.Without economic development,we would remain backward.And without environmental protection,we would lose our homes.It seems that the best solution is to develop environ-mental-protection-oriented enterprises so as to "kill two birds with one stone".
參考譯文：
發(fā)展經(jīng)濟還是保護環(huán)境?
有些人認為我們應該首先發(fā)展經(jīng)濟。只有進一步協(xié)調(diào)經(jīng)濟的發(fā)展，我們才能消除貧困，實現(xiàn)總體發(fā)展的目標。否則許多人，尤其是農(nóng)村人，可能會生活在貧困之中，小孩因支付不起費用而輟學。
相反地，也有人主張優(yōu)先保護環(huán)境。他們的觀點是，迅猛而且無限制的發(fā)展導致了現(xiàn)在世界上多數(shù)地方的污染問題。如果不解決問題，有朝一日我們將失去生存的空間，還談什么發(fā)展經(jīng)濟。
我認為發(fā)展經(jīng)濟和保護環(huán)境都是我們的`當務之急。不發(fā)展經(jīng)濟，我們會落后;不保護環(huán)境，我們會喪失家園。 似乎最好的策略是建設保護環(huán)境為導向的企業(yè)，發(fā)展與保護并舉。
