The End of the Green Revolution
The Green Revolution has brought us agricultural abundance. However, it has reached the end of its useful life. Why?
- It depends on large quantities of cheap oil for machinery, pesticides and chemical fertilizers. Peak oil means oil will become scarcer and more expensive.
- It strips topsoil each year. We are almost to the point where topsoil is too thin to grow crops.
- The fertilisers cause eutrification of the rivers.
- Monoculture encourages pests to evolve resistance to pesticides.
- Pesticides are harming humans and non-target species.
- It requires abundant cheap water. With global warming, much of our agricultural land is becoming dryer.
Happily there are alternatives that still produce high yields. We need to start switching over. Unfortunately, corporations don’t want change, even if it kills us.~ Roedy (1948-02-04 age:69)
