Unit 10 Agriculture

Farming for the Future

[1] Every year, more people face poverty and hunger and more of the earth's resources are ruined. The problems are enormous, but many experts believe that the situation is not hopeless. The solution will require big changes in how we think about agriculture, food, and our planet.

[2] First of all, farmers everywhere need to develop methods that are less destructive to the environment. The change from single crop farming to a mixed crop system would be one important step. The planting of several different crops improves the soil and helps prevent erosion. Erosion could also be prevented by planting trees to protect the fields from the wind. Another way farmers could improve the soil is to avoid deep plowing. In fact, only a slight plowing is necessary if proper methods are used.

[3] If the soil were treated better, farmers would not need to use chemical fertilizers. They could use natural animal and vegetable products instead. With mixed crops, farmers would need fewer toxic chemical insecticides. They could use biological methods of controlling insects and disease.

[4] 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.

[5] 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.

[6] Industrialized countries could use their economic resources to help bring about these changes. They could make some changes in their own policies. At present, much food is wasted in these countries for political reasons. In Europe and in North America, tons of fruit and dairy products are thrown away every year. Eating habits, too, could be changed in these countries. For example, people often eat foods from distant places instead of local foods. The transportation of the imported foods adds to the global pollution problem. People in industrialized countries also eat a lot of meat, especially beef.
