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.
