Farmers could also help save the earth's precious supplies of water and petroleum. To save water, they could plant more water-efficient plants instead of the standard types of wheat or corn. They could also use watering systems that are much less wasteful. To save petroleum, farmers could make use of bio-gas generators which could be fueled by the vegetable and animal wastes of the farms. In less-developed countries, bio-gas generators could reduce the need for firewood and so help save forests, as well. In less-developed countries, the small farmers need help. They need to learn more about crops that are better suited to local conditions. They need to learn how to limit erosion and make the best use of their resources. These farmers will never be successful without land and economic reform. This should be the aim of governments and international agencies. The current industrial and cash crop policies are only making the situation worse.
農(nóng)夫們也能幫助節(jié)約地球上珍貴的水和石油供給。節(jié)水方面，他們可以種植更多的節(jié)水植物代替?zhèn)鹘y(tǒng)的小麥或玉米。他們也可以使用更加節(jié)水的灌溉系統(tǒng)。節(jié)油方面，他們可以使用沼氣生產(chǎn)裝置，這種裝置可用農(nóng)場(chǎng)內(nèi)的蔬菜殘?jiān)蛣?dòng)物廢物做燃料補(bǔ)充。在一些齊欠發(fā)達(dá)國(guó)家，沼氣生產(chǎn)裝置可以削減木柴的需求，同時(shí)也有助節(jié)約森林資源。 在這些欠發(fā)達(dá)國(guó)家，那些小農(nóng)戶需要幫助。他們需要了解更多更適合種植在當(dāng)?shù)氐霓r(nóng)作物的情況。他們需要學(xué)習(xí)如何限制腐蝕和充分利用他們的資源。這些農(nóng)民離開(kāi)了土地和經(jīng)濟(jì)改革是永遠(yuǎn)不可能成功的。而這應(yīng)該成為政府和國(guó)際公眾服務(wù)機(jī)構(gòu)的目標(biāo)。目前的工業(yè)化的行政型態(tài)和和經(jīng)濟(jì)作物政策正使情況越發(fā)糟糕。 ——譯文來(lái)自: 彼岸楓雪非
