保護(hù)環(huán)境

過(guò)去，人們不必?fù)?dān)心保護(hù)環(huán)境的問(wèn)題。 因?yàn)槟菚r(shí)地球上人口稀少，自然資源似乎取之不盡。

如今，一切都改變了。世界變得擁擠異常。我們正在耗盡我們的自然資源，有毒化學(xué)制品的使用也正污染著環(huán)境。如果我們繼續(xù)這樣下去，地球上的生命將不復(fù)存在。

我們都知道如果從海里捕捉太多的魚，海里就不會(huì)再有魚了。但是，現(xiàn)代化的捕魚技術(shù)使得捕魚量越來(lái)越大。我們都知道如果砍伐太多的樹木，森林就會(huì)消失。但是，我

們?nèi)耘f使用強(qiáng)大的機(jī)械砍伐越來(lái)越多的樹木。我們都知道如果河水被廢棄物污染的話，我們只有死路一條。但是廢棄物仍然源源不斷地進(jìn)入河里

我們知道，人口繼續(xù)照現(xiàn)在這個(gè)速度增長(zhǎng)的話，不出幾年，就會(huì)發(fā)生食物短缺。我們?cè)撊绾谓鉀Q這些問(wèn)題呢?

如果我們多吃蔬菜，少吃肉類的話，我們就會(huì)有更多的食物。因?yàn)橥瑯哟笮〉耐恋厝绻�種莊稼的話會(huì)比養(yǎng)殖動(dòng)物多養(yǎng)活五倍多的人。

如果我們學(xué)會(huì)再利用的話，自然資源就能持續(xù)更久。

如果人們使用現(xiàn)代化的生育控制方法，世界人口就不會(huì)增長(zhǎng)如此迅猛。

最后，如果我們能夠教育人們都意識(shí)到這些問(wèn)題的話，未來(lái)我們就會(huì)有一個(gè)更好、更潔凈的星球。
