Through selective breeding, Norman Borlaug, an American biologist, created a dwarf variety of wheat that put most of its energy into edible kernels rather than long, inedible stems. In addition, the environment was negatively affected through increased pollution and erosion, more pressure on water systems, and higher rates of energy consumption. Link to this page: green revolution They cover food security and economic development: how science is applied to solve problems of poverty, drought, and famine; science and food security: how science is used to generate efficient and optimal agricultural outputs; and food security and ecological balance: how the gains of green revolution are impacted by climate change, how science will be helpful in ensuring sustainable food security, and a roadmap from green revolution to ever- green revolution.
