Cooperatives comprise individuals who have pooled resources to provide input, output, and capital resources to members at a low cost. Food production must keep pace with population growth and distribution methods. By selectively breeding animals (breeding those with desirable traits), farmers increased the size and productivity of their livestock.Cultures have been breeding animals for centuries—evidence suggests Mongolian nomads were selectively breeding horses in the Bronze Age. Select from these resources to teach your students about population characteristics. They have put herb-based poisons on crops, handpicked insects off plants, bred strong varieties of crops, and rotated crops to control insects.

GMOs that have genetic material, or DNA, from other species are called transgenic organisms.A gene from an Arctic plant, for example, could be added (spliced) into the DNA of a strawberry plant to increase the strawberry’s resistance to cold and thus extend its growing season. To produce high yields, the new strains required chemical fertilizers, pesticides and irrigation.

The Corn Belt is the area of the northern Midwest where most of the nation’s corn crop is grown. There, they are kept in pens and fed grain and vitamin supplements until they reach market size. FAO or CDB is not responsible for the content or accuracy of this translation. Our sciences hold the key to meeting some of the greatest challenges facing our nation and the world: food safety and security, natural resource management, energy production, and climate resiliency. To harvest the crop, farmers use a mechanical harvester that picks the ears of corn and shells them into a bin.Little of the corn grown in the Corn Belt is for human consumption. Food surpluses allowed people to work at other tasks unrelated to farming.Agriculture kept formerly nomadic people near their fields and led to the development of permanent villages.
