求一篇因人口引起的环境问题以及解决办法的英文

Those with only an environmental perspective can argue persuasively that consumption and waste in the developed world is the driving factor behind many global environmental problems,such as ozone depletion,acid rain and climate change.For example,industrialized countries,with less than one-fourth of the world's population,currently account for about two-thirds of the world's carbon dioxide emissions.The higher per capita consumption and waste production in the industrialized world has led some to conclude that all that is necessary is to reduce the per capita consumption in the West.This is,of course,part of the solution.But with populations of many Western countries continuing to grow (especially in the United States),reduction of total emissions of greenhouse gases is made more difficult.On top of this,the burgeoning populations of developing and industrializing countries want access to the automobiles,furnaces,manufactured goods and other items that are major contributors of greenhouse gases.And often these poorer countries reject the technologies to reduce emissions as too expensive.In order to improve the standard of living,some poor countries are trying to increase the ability of their people to consume resources.
As a result of very rapid growth rates of population and of energy use by developing countries,the U.N.panel on climate change projects that,by 2025,developing countries could be emitting four times as much carbon dioxide as the industrialized countries do today.Reducing population growth rates in the developing world would make a major difference in this problem.
A maximum sustainable population at any given level of standard of living would be one that would have no effect on the earth's long-term carrying capacity.As per capita rates of consumption and waste production reach critical levels,the carrying capacity of the earth,in terms of numbers,diminishes.Combining rapid population growth with growth in per capita consumption is a sure formula for disaster.
There are no environmental threats that would not be alleviated by rapid stabilization and perhaps ultimate reduction in human numbers.Continued and accelerating population growth is making all the environmental problems more severe,if not insolvable.
