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.
农夫们也能帮助节约地球上珍贵的水和石油供给。节水方面，他们可以种植更多的节水植物代替传统的小麦或玉米。他们也可以使用更加节水的灌溉系统。节油方面，他们可以使用沼气生产装置，这种装置可用农场内的蔬菜残渣和动物废物做燃料补充。在一些齐欠发达国家，沼气生产装置可以削减木柴的需求，同时也有助节约森林资源。 在这些欠发达国家，那些小农户需要帮助。他们需要了解更多更适合种植在当地的农作物的情况。他们需要学习如何限制腐蚀和充分利用他们的资源。这些农民离开了土地和经济改革是永远不可能成功的。而这应该成为政府和国际公众服务机构的目标。目前的工业化的行政型态和和经济作物政策正使情况越发糟糕。 ——译文来自: 彼岸枫雪非
