Environmental Challenges of the 21th Century.

According to Juniper (2007), "our planet is utterly unique - a blue, white and green gem suspended in the gaping black emptiness of space" (p.8, para1), and some of us would think we are really lucky to live on this precious earth. But he also mentioned that "The Earth could so easily have remained like there other lifeless worlds" (p.8, para4), so we should also take care of our earth. Let us look at what our earth is now: first, as Trombly (2007) mentioned "There is limitless and practically useful energy anywhere you stand or sit" and "From the threat of global warming to the decline of endangered species, environmental issues are now at the forefront of the human agenda - and not a second too soon.” We can see now the environmental problem is really critical. For example, according to Evans (2007), CO2 is the main cause of global warming, but in our daily life, we know that the fire of fuel and polymer even other things would produce CO2. Hence, one solution to reduce the speed of global warming or solve this problem is to make some measures: set up the opinion of global warming in human minds, do what people can do in their daily life to contribute their energy and build up some green organization to reduce this problem. Firstly, knowing the reason for global warming is really necessary. Starting from the basic behavior, we should build up some activities to propagate that CO2 is the main culprit of global warming and some procession would produce it, such as the fire of coal, oil or plant, and then let people know the bad effects of global warming. At the same time, we should also point out that forest can make many good effects on reducing the amount of CO2 in the world. After doing these, most people would know the meaning of reducing the global warming. Hence, making people knowing the reason for global warming and the meaning of reducing it is really necessary for us to do. Secondly, if every factory in the world produces a little less CO2, the increasing rate of CO2 would reduce a lot. We can see that our world is an industrial world now and there exist many industrial factories. If every person in factories did what they can do for our environment, such as using advanced equipment for refreshing the air before letting them out, the temperature would reduce or at least remain balanced. As a consequence of contributions from factories, the warming phenomena would have a great change. Lastly, some behaviors from governments are really necessary for solving this problem. Greenhouse gases are emitted as a result of the energy we use by driving and using electricity and through other activities that support our quality of life like growing food and raising livestock. If governments build up some organization for our environment, such as organization for planting trees, green fuels corporation and so on, and then encourage some volunteers to join in them to produce more plants and produce some green fuels rather than coal or oil... then our world would become green in some years later. In summary, the government should take some above necessary measures to solve this problem. In conclusion, it is possible to reduce the global warming with the support from every part in the whole society. The world is our family and protecting it is protecting ourselves, so what we do for our earth is really important. Reference Juniper,T.(2007).Saving planet Earth. London: Collins.

the suitable method for my country--China

With the development of the economy in China, the pollution of the environment is becoming a critical problem. Facing these wastes, whether the government of China should choose landfills, incinerators or “zero waste” is really hard to decide. But considering the environment and economic factors, the government of China might consider “zero waste" as a better method to solve this problem. But what is "zero waste"? "Zero waste is a grassroots movement from local authorities and people,” so some materials can be recycled (collins, 2002).
Comparing with other methods, "zero waste" makes the materials recycled and saves the limited source for our human beings, so it is really an economic development besides of the environmental conscience. More than what we can expect, It is a quiet revolution where non-profit community groups are turning waste into jobs, so some person would make life in this way. It is true that "zero waste” may not be achievable, but if we get anywhere near, then the benefit for health and jobs will be enormous. In contrast, land filling not only wastes sources, but also pollutes the environment, so it will indirectly make bad effects on our health and daily life. What is worse, land filling is also an uneconomical behavior due to the loss of the recyclable materials. Hence, we should choose "zero waste policy" rather than land fillings or incinerators due to environmental protection, source savings, source recycling and even economy development in China.

review about the Saving Nature,But Only for Man

As we all know that, we could catch fish in the river with our hand in a few years ago, but now we even can not catch any fish using fishnet. What happens and what lead to this phenomena? Maybe some person would say that the pollution is really critical now and that is the reason for it, but i want to ask what lead to pollution and who is the main cast in this behavior. I think the report, named Saving Nature,But only for Man, gives us the answer. The most part of reasons for the pollution to the nature comes from our human.
As the report maintioned, now most people like to show that they are lovers of mother nature, but it also indicates that we have make the pollution to our mother nature. In this report, we can see that it is calling people to learn more about nature and leading people to know that nature is not so benignity. What is more, we can see that we should take care of nature, not the nature charge us, so we should make balance with nature, then we can get our kind nature back. But what should we do for our nature in the report maintioned?
In the report we can infer that we should know which side is more meaningful such as between family and owl, we should choose family, so we should take care of the livelihood. And now our fate and that of nature are inextricably bound up, so we should take measures for our nature and balance the against health. What we should do for the threatened atmospheric is on the way for our human to do. The sentimental environmentalists will call some saving nature with a totally wrong frame of mind, so they should build up their new mind and do some thing for our nature.
Green house,Ozone depletion are being the most curious problems , so our human should practice sane environmentalism and do what we can do for our nature.
