still put into rivers.

過去，人們不必?fù)?dān)心保護(hù)環(huán)境的問題。 因?yàn)槟菚r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，海里就不會再有魚了。但是，現(xiàn)代化的捕魚技術(shù)使得捕魚量越來越大。我們都知道如果砍伐太多的樹木，森林就會消失。但是，我們?nèi)耘f使用強(qiáng)大的機(jī)械砍伐越來越多的樹木。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)在這個速度增長的話，不出幾年，就會發(fā)生食物短缺。我們該如何解決這些問題呢?
如果我們多吃蔬菜，少吃肉類的話，我們就會有更多的食物。因?yàn)橥瑯哟笮〉耐恋厝绻N莊稼的話會比養(yǎng)殖動物多養(yǎng)活五倍多的人。

如果我們學(xué)會再利用的話，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，世界人口就不會增長如此迅猛。
最后，如果我們能夠教育人們都意識到這些問題的話，未來我們就會有一個更好、更潔凈的星球。
