Air and water are biological survival indispensable, if both of the person or both were destroyed, and the ecological environment will lose balance, biological survival will face huge challenges, such as the animals and plants survival, some biological survival adverse off balance, or a large number of breeding, or on the population has dropped sharply even cause some species disappear from the earth's surface. As in humans, this case is extremely serious, a big impact on human life and even threatened to human survival. 1, due to damage the ecological balance, natural disasters, will increase to human cause property and personnel loss. 2, is accompanied by climate change, the temperature change can be very unstable, people all aspects of life will be affected, some deadly diseases are more difficult to control, the disappearance of some species 3 will accelerate and the deterioration of the state, which is no more problems, in a short time the recovery.
Plants and animals is the fundamental source of food, water and air purification can play the important role of destruction, once a species, reduce or perish, can cause biological, a food chain rupture, and the more heterogeneous article related species survival difficult or even extinction. Also with the global environment also can worsen, carbon dioxide in the air increased, some ingredients can't get balance, oxygen amount will be reduced, many animals can't survive.
Animal is also a very important biological a, though it for the environment effect is very small, but once be destroyed, for humans will very adverse, animal species of animal diversity, reduce reduce, can make more vulnerable to the animal kingdom cannot restore complete and damage, thus affecting the human survival and development.
Environmental pollution is refers to the humanity, directly or indirectly, to the environment than its emissions self-purification capability of matter or energy, so that the quality of the environment, to reduce human's survival and development, ecological system and property adversely affect phenomenon. Specific include: water pollution, air pollution, noise pollution, radioactive pollution, etc. Along with the science and technology level of development and the improvement of people's living standard, the pollution of environment is growing, especially in developing countries. Environmental pollution is more and more become world each country one of the common project.
Proud of water saving--shut up tap at any time, don't let water flow empty.
Monitoring water-water source protection is to love life
Water use--let water reuse
Stop drip-check and repair the tap
Careful with cleaner-as far as possible with soap, reduce water pollution
空气与水都是生物生存必不可少的,如果二者中的一者或两者遭到破坏,生态环境将失去平衡,生物生存将面临巨大挑战,如对动物与植物生存不利,有的生物生存失去平衡,或大量繁殖,或种群数量上急剧下降甚至造成一些物种从地球上消失.对于人类来说,这种情况下也是极为严峻的,会对人类生活造成很大影响,甚至威胁人类生存.1,由于生态平衡破坏,自然灾害增多,会对人类造成财产与人员损失.2,也伴随着气候的改变,温度变化会很不稳定,人们生活方方面面都会受到影响,某些致命疾病也更加难以控制3,一些物种的消失会加速和态的恶化,产生更多问题,也是不可在短时间恢复的.
植物是人与动物食物最根本的来源,了能起到净化空气与水体的重要作用,一旦破坏,某物种减少或灭亡,会造成生物界某条食物链断裂,更多相关联的物种生存困难甚至也随着灭绝.全球环境也会恶化,二氧化碳增多,空气中一些成分无法得到平衡,氧气量也会减少,很多动物无法生存下去.
动物也是生物中极为重要的一支,虽说它对于环境的作用很小,但一旦被破坏,对于人类将十分不利,动物物种的减少,动物多样性降低,会使动物界更容易遭到彻底而无法恢复的破坏,从而影响到人类生存与发展.
环境污染是指人类直接或间接地向环境排放超过其自净能力的物质或能量,从而使环境的质量降低,对人类的生存与发展、生态系统和财产造成不利影响的现象。具体包括:水污染、大气污染、噪声污染、放射性污染等。随着科学技术水平的发展和人民生活水平的提高,环境污染也在增加,特别是在发展中国家。 环境污染问题越来越成为世界各个国家的共同课题之一。
节水为荣——随时关上水龙头,别让水空流。
监护水源——保护水源就是爱护生命
一水多用——让水重复使用
阻止滴漏——检查维修水龙头
慎用清洁剂——尽量用肥皂,减少水污染

Save the environment , Save ourselves.
My fellow classmates,
Good morning. Today I'd love to introduce my topic here--- "Save the environment , Save ourselves".
Nowadays many people are on fire for fighting against unfair treatments to colored people, women , animals and so on. But today I will talk about fighting for the rights of the natural.
Always we complain about the environment being destoried by our human-beings seriously, but most of us have not noticed we ourseleves are part of the polluters, too. For example. On one hand we advocate not litter here and there, on the other hand, we often wrap ice-cream papers on the ground optionally. For instance, some factory managers build their houses in the country with beautiful scenery nearby, but at the same time their factories is pouring dirty water into the river secretly... Thus, although everyday we are call in others to improve the environmental consciousness, the pollution to the environment, the hurt to animals in danger occurs still.
There are many problems about environmental protection in recent years. The most serious problems are the serious pollution of air, water and soil we live by. Although the environment doesn't have a mouth to deprecate what humans have done to her, she retaliates through action.
Moreover, in the early years the Chinese cut down large quantities of trees, at the source of the yellow river, which led to the disappearance of big forests and terrible floods. As a result, the Huangtu plateau which was once covered with grass and forests was turned into barrens that supported fewer plants. Another example was in several developed countries. Because many chemical factories discharged poisonous gas without filtering it, cities were covered with so much poisonous gas that people were killed by the air they breathed in. The polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.
What horrible scene! What we are suffering is only a small part of what the nature once suffered. If we don't take measures to show our respect to the environment, I am sure that we will have to face an increasingly awful situation.
In my opinion, Since we are all looking forward to beautiful surroundings, why can't we make and protect it ourselves? Many people always blame on others who pollute the environment but they forget he himself is one of the polluter, too! As we all know, We have only one Earth, we are not the conquer of natural but the son of her together with a lot of other creatures. If they are damaged, without our brothers and sisters, how can we live then? Therefore, Measures should be taken to protect the environment on which we are relying on .
The environment must be linked with the social ethics. Everyone must fulfil his responsibilities and obligations to protect the environment.
And at last , I'd like to say, Only by changing the way we treat the environment can we get along well with it. Only by saving the environment can we save ourselves.!
That's all. Thank you for listening!
