　　篇一：解決人口增長(zhǎng)英語(yǔ)作文

　　Progress in science and the improvement of living conditions have led m the rapidgrowth of the world population. Modern medical science, for example, has made it possible for babies to grow up healthily and for people to live longer.With improved living conditions, particularly in the countryside, people tend to have larger families. As a resuit, the world population has increased so rapidly that it has now exceeded 5 billion. But the overgrowth of population presents a threat to the existence of human society. A large population demands a great deal of food supply and shelter space. However,the limited productivity and scarce natural resources can hardly meet the needs of the ever-Increasing population. Thus in the long run, the overgrowth of the world population will only harm mankind.4ia英語(yǔ)作文網(wǎng)

　　控制人口

　　科學(xué)的進(jìn)步和生活條件的改善導(dǎo)致了世界人口的迅速增長(zhǎng)。譬如，現(xiàn)代醫(yī)學(xué)可以使幼兒健康成長(zhǎng)，使人們長(zhǎng)壽。由于生活條件的改善，特別是農(nóng)村生活條件的改善，家庭人門日漸增多。結(jié)果，世界人口增長(zhǎng)如此迅猛以致于現(xiàn)在人口超過(guò)了50億。

　　但是，人口過(guò)分增長(zhǎng)對(duì)人類社會(huì)的存在構(gòu)成了威脅。大量的人口需要大批的糧食供給和大量的住宅。然而，有限的生產(chǎn)能力和不足的自然資源幾乎不能滿足日益增長(zhǎng)的人口的需要。因此，從長(zhǎng)遠(yuǎn)的觀點(diǎn)看，過(guò)多的世界人口將會(huì)危害人類。

　　為了保證人類社會(huì)的穩(wěn)定發(fā)展，人類必須意識(shí)到人口迅速增長(zhǎng)所造成的后果和執(zhí)行計(jì)劃生育方針的重要性。只有采取有效措施，人類社會(huì)才能穩(wěn)步發(fā)展，才會(huì)有光明的未來(lái)
