As is seen from the two graphs, it is clear that with the rapid growth of U.S. population from 1800 to 1990, the number of its wildlife species no longer existing soared during the same period. Naturally, we can draw the conclusion that the sharp decline of wildlife species resulted from the population growth.
Two reasons may account for this phenomenon. To begin with, as the population grows, people consume much more natural resources, which often leads to excessive hunting. Second, with the increase of human activities, modern people take up more and more space. Which has a great impact on other species. Finally, the problem of pollution becomes more and more serious with the development of modern industry. More and more animals have to adapt themselves to the decaying environment or move to a totally different place, but not all of them are fortunate enough to survive the changes.
Solving this problem calls for, above all, the government’s efforts to control population growth, to decrease industrial pollution and to enhance the laws to forbid wildlife hunting. Moreover, common citizens should be aware of this ecological crisis and take on the responsibility of wildlife protection. In a word, only when the government and the common people make joint e f forts can we hope to find a satisfactory solution to this problem.

從這兩個圖,很明顯,美國人口的快速增長從1800年到1990年,其野生動物物種的數量不再現有同期飆升。自然,我們可以得出結論,野生動物物種的急劇下降導致的人口增長。
兩個原因可以解釋這一現象。首先,隨着人口的增長,人們消耗更多的自然資源,這常常會導致過度的狩獵。其次,隨着人類活動的增加,現代人越來越多的空間。有一個偉大的對其他物種的影響。最後,污染變得越來越嚴重的問題,隨着現代工業的發展。越來越多的動物必須適應的環境或搬到一個完全不同的地方,但並非所有都幸運地在變化中生存下來。
要求解決這個問題,最重要的.是,政府的努力來控制人口增長,減少工業污染和提高法律禁止野生動物狩獵。此外,普通公民都應該意識到這種生態危機和野生動物保護的責任。總之,只有當政府和老百姓共同e f堡壘我們希望能找到一個滿意的解決這個問題。

第三篇：關於人口問題的英語作文
The first fifty years of the next millennium will be critical for the world's population. By 2050 population growth should have leveled off, but by then we'll have 10 billion people--two-thirds as many again as we have rate of population growth is something we can choose right now, though: it's 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 explosion, 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 women's 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 people's 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 next 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 don't 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 we'd destroyed the natural environment in the process.

第一個五十年的下一年世界人口將至關重要。到2050年人口增長應該趨於平穩,但那時我們將有100億人——我們今天三分之二儘可能多的再次。人口的增長是我們可以選擇現在,儘管:這不是剛好,但人類選擇的問題。選擇是一個複雜的,有許多變量,但它仍然是一個選擇。
如果我們想避免人口爆炸,我們現在應該採取行動或者幫助貧窮國家。他們需要更好的政府,更好的制度,更好的勞動力和資本市場,更好的學校。
任何增加的價值,女性的時間和增加了的成本照顧一個孩子會讓一個女人更不可能有孩子。自大家庭往往被視爲安全網疾病和衰老,改善貧困人口獲得保險、退休金和福利機構也有重大影響。這可以簡單如農村信用,提供儲蓄的一種手段。最後,還有教育,對於女性來說,也許更重要的是,對於下一代的孩子。
有采取這些步驟,但似乎有些國家不認真努力。如果我們不能實現,我們將肯定不是控制人口。
說,我不覺得悲觀,我們將耗盡資源:我們正變得更有效地生產糧食的速度比人口增長的速度。然而,風險,我們將有效地破壞環境,世界將不再是一個吸引人居住的地方。這確實是一個可悲的結果,實現了人口的平衡卻發現在這個過程中我們破壞了自然環境。
