China has only 7 percent of tile world farmland, but it successfully feeds 22 percent of the word population. It has the largest irrigated area of the fanaland in the world and grows more than a third of rice and other crops of the world. Fish farming is also important, so fresh-water fish can be produced wherever you hive. Vegetable waste is used to feed pigs and chickens in the country. Gas also is produced by human and animal waste there, and it is used to heating and cooking. Using waste can make the environment around us cleaner and cleaner.
中國(guó)的農(nóng)業(yè)
中國(guó)僅擁有世界耕地面，面積的7％，卻成功養(yǎng)活了世界22％的人口，而且中國(guó)是世界上灌溉耕地面積最多的國(guó)家，種了占世界三分之一以上的莊稼。漁業(yè)也很重要，無(wú)論你住在什么地，你都會(huì)發(fā)現(xiàn)淡水魚。在農(nóng)村，萊葉、萊根等被用來(lái)養(yǎng)豬和喂雞，而人類和動(dòng)物 的糞便也可用于生產(chǎn)沼氣、取暖、做飯。廢物利用可以使我們周圍的環(huán)境越來(lái)越干?
