45岁以后血压多少是正常值。Todays society is a highly developed technological society. However, the shortcomings in the development process are obvious, such as: carbon dioxide, and environmental pollution. But the most serious should be the carbon dioxide problem. Now the problem of global warming because of excess emissions of greenhouse gases. Excessive amount of carbon dioxide emissions, creating a diversified economy and La Nina phenomena lag disorder. Two levels of glaciers melting, polar animals lose their chance of survival at the same time, will lead to rising sea levels, many coastal cities into the water did not result in a few years later. Therefore, we must take the necessary measures to reduce the environmental impact of carbon dioxide.For example: tree-planting activities, reduce fossil fuel use, we can from our own, to promote low-carbon living.In this day and age, environmental degradation presents great danger to the public. People in my country, and other places, have to bear polluted water and haze day after day. As public awareness of the need for environmental protection grows in these countries, it is urgent to learn how to establish a green life style.To achieve a green life style, we must adjust our behavior. This can be done even with simple things. For example, we could sort out our trash for better recycling. At home, we can use lights and other electricity only when needed. We should properly maintain air conditioners twice a year so they will run efficiently, and, even more importantly, make sure doors and windows fit properly and are sealed so that we can use less energy in heating and cooling. Other simple steps that make a big difference include using public transportation instead of driving private cars. Commuters can choose to take buses, subways or share cars with others, which not only relieves traffic jams but also reduces gas emission.In my mind, it is high time to establish a general concept of sustainable development and green life style in China. The Earth has provided humans what they need; it is time to pay back. Only through a green life, can we ensure that we and our children live in an environment with green water and mountains, without traffic jams, and in an era with better living habits.Presently, a new lifestyle called low carbon life is spreading every corner of our country. The concepts of low carbon are low energy and no waste. It is such a significant project that I cant wait to present my ideas on how to promote it.On the first place, a no-car day is supposed to set up every week in our school. Because cars not only cause serious air pollution but also waste energy. On no-car day, neither students nor teachers are allowed to drive to school. Meanwhile, just walk, jump, cycle or run. Use our legs and enjoy the fun.On the second place, we had best not use plastic bags any more. No one can stand the “white pollution”. So, it is wise to use bags which can be reused again and again.Finally, one thing that we should keep in mind: every big thing comes from the subtle. Therefore, as students, we ought to turn out the lights the moment we leave, turn off the tap in time, and reuse our textbook and so on.All in all, it weighs greatly for all of us to put the low carbon lifestyle into practice. Just set our mind to these: no-car day, no plastic bags, and no waste. Lets do it now.There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to peoples health.The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.Environmental protection needs the maintenance of all of us. Only if we are active to maintain. Our environment will become better.Once, father, mother and I go to the park for a walk, just going to the park to see some of the white plastic bag fell to the ground, is very obvious. "The litter is not civilization", my in the mind in blame them. My eyes are bright, by the way, I am a little green guards, should take good care of the environment. I bent down and picked up to throw garbage into the trash. Mother said: "with the hand to pick up more health, with branches clip". So, I use two branch, with his hands a clip, garbage will obediently followed I go. A bridge, lets go to the park to see rubbish was strewn all over the grass, cleft. As they walked along, I pick up. Went to the amusement park, at first glance I saw a white stone chair plastic bags, they like a terrible enemy attack us. I run to get rid of them one by one all. I found on the lake and some white plastic bags, Ill give it all up, but, I catch a have a plastic bag, dad said: "let me help you." So, my father took my hand, I go to pick another hand holding a branch, finally got the scoop up plastic bags. I like the battles of soldiers happy.Though today just me and my parents clean up the garbage, but I believe that people will take good care of the environment, there will be more people to do the green small guard.In order to support Beijing to hold the 2008 Olympic Games and protect our environment, an activity was organized by the Young League and Students Union of our school during the week from June 3rd to June 8th.All the students in the senior grades took active part in it. Some students cleaned the playground, watered the young trees andflowers, and removed weeds. Some students collected waste paper, old books, empty cans and old toys.They had them sorted and sent them to the recycling center.The activity is really instructive. Now we all have realized how important protecting the environment is.There are still many proble of environntal protection in recent years. One of the st serious proble is the serious pollution of air, water and soil. the polluted air does great harto peoples health. The polluted water causes diseases and death. What is re, vegetation had been greatly reduced with the rapid growth of dern cities.To protect the environnt, governnts of ny countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environntal pollution. Therefore, governnts are playing the st iortant role in the environntal protection today.In opinion, to protect environnt, the governnt st take even re concrete asures. First, it should let people fully realize the iortance of environntal protection through education. Second, ch re efforts should be de to put the population planning policy into practice, because re people ans re people ans re pollution. Finally, those who destroy the environnt intentionally should be severely punished. We should let theknow that destroying environnt ans destroying nkind theelves.Nowadays,with more and more serious problem such as the global increasing temperture,the melting ice and the rising sea―levering,people are recognizing the important of developing the low―carbon economic now.There are many ways we can do to reach the loe―carbon economic.Fristly,discovering others fuels which is more clean and more green to instead of the using of carbon.Secondly, we should have the save―energy conscious and do something which we can make,for instance,using the bus ranther than car when you go out,re―use the thing that can be recycle used,reducing the use of plastic bags.Last but not least,we should plant more trees or other greenplants,in which way we can not only improve the environment,but also can make our home more beauty.In my opnion, the most important thing to reach the low―carbon economic is everyone must try their best do what they can do for it.Once everyone have the sence of low―carbon economic and have the action by themselves ,it will be earlier to reach it.The earth is our home, we should protect the earth. Now in some areas there have been landslides, typhoons, forest fire, river pollution, destruction of the ozone layer, air pollution...... We have to continue to suffer from the nature of the punishment.How can we protect our homeland? We should plant more trees, do not indiscriminate felling of trees, do not throw garbage, pay attention to health, to keep the campus clean. A variety of flowers and plants, water conservation, protection of animal, no damage to water...... Said we must do. We want to become rich in water resources, living trees, no desert, no disaster, marine products, lawn area larger...... Let us change the environment, change the net, greener, more beautiful environment.Protect environment, everyones responsibility! Only when each of us to give a bit of environmental protection themselves, can make the home more beautiful tomorrow.Whats more, we should realize that only from our planet can we obtain our sheltering, food, cloth and so forth.To everyone on our planet,Over the past years, floods, droughts, landslides, and dust-storms have frequented our planet, the only habitat of human beings. Several days ago, tsunami(海啸) has swept the Southeast Asia, which has caused enormous damage. All these have sounded an alarm to human beings.The destruction which is caused by human beings has aroused peoples concern all over the world. If we pay no heed to the present destructive human activities, our planet will become of tomb instead of cozy home. Whats more, we should realize that only from our planet can we obtain our sheltering, food, cloth and so forth.Counter-measures must be taken to curb the destruction caused by human beings. Most importantly, laws must be established to punish those who are involved in destructive conducts. 。
