Man is constantly trying to use technology to intensify food production. To what extent is technology the answer to world hunger. Using of technology to intensify food production includes choosing seeds of better qualities, using modern irrigation methods and using chemicals such as fertilisers, pesticides and herbicides to increase the outputs of crop fields because plants become more restricted to dry seasons, insects as well as famers are able to grow more rounds of crops in a year. This also includes using of modern machines like tractors and harvesters to reduce the number of man power needed working in crops fields, this increase the productivity in food production. This intensification in food production help reduce the world hunger and try to keep everyone's calorie intake above the average, 2586 kilocalories per person daily. I agree that technology is the answer to world hunger to a certain extent. High Yielding Varieties(HYVs) improved breeds of rice, wheat and other cereals developed by crossing-breeding a broad range of cereal strains. They have valuable traits such as pest resistance or faster growth duration compared to normal cereals. For example, IR58'wonder rice' which has shorter growing period is resistant to pests and diseases. Using HYVs, China's rice output was more than doubled from 1961 to 1992. Also, modern irrigation is introduced as a modern technology to intensify food production. Irrigation is the practice of supplying water to the land through artificial means which enable farmers to control the amount of water supplied to crops. It helps land to be fertile and maintain flooded conditions, no longer need to depend on rain or crops can be grown, thus a higher yield is achieved. Besides, chemicals such as fertilisers help to add nutrients to the soil to encourage growth of crops. Toxic chemicals can be used to destroy pests which may affect crop growth. Use of fertilisers may result in growth of weeds, so herbicides could be used to...
