考研英语作文2400字：The World s Population(世界人口) the world s populationthe first fifty years of the net millennium will be critical for the worlds population. by 2050 population growth should have leveled off, but by then well have 10 billion people--two-thirds as many again as we have today.the rate of population growth is something we can choose right now, though: its not something that just happens, but a matter of human choice. the choice is a complicated one,with many variables, but it remains a choice. if we want to prevent a population eplosion, we should take action now -or assist the poorer countries to do so. they need better government, better institutions, better labor and capital markets, better schools. anything that increases the value of womens time and adds to the cost of caring for a child makes a woman less likely to have that child. since big families are often seen as safety nets for illness and old age, improving poor peoples access to insurance, pensions and welfare institutions also has a major impact. this can be as simple as rural credit, providing a means of saving. finally, there is education--both for women and, perhaps even more important, for the net generation of children. these steps are there to be taken, but there appear to be some countries that are not seriously trying at the moment. if we cannot achieve that we will certainly not control population. that said, i dont feel pessimistic that we are going to run out of resources: we are becoming more efficient at producing food faster than the rate at which population is increasing. there is, however, a risk that we will wreck the environment so effectively that the world will no longer be an attractive place to live. that really would be a dismal outcome, to reach world population equilibrium only to find wed destroyed the natural environment in the process. 世界人口 本作文共2页,当前在第1页12 |
