“In Indonesia, a million farmers have gone through informal ‘farmer schools,’ learning from their neighbors new ways to control bugs by encouraging their natural pests. ‘The yields of rice they get are roughly the same,’ says Pretty, ‘and of course they’re saving lots of money on pesticides. But the big boost comes from the fact that once you stop using pesticides you can grow fish in the rice paddies. The fish help to circulate nutrients, they eat a lot of pests themselves—and you’ve got seven hundred kilograms of fish per hectare per year to eat or to sell. That’s a lot of protein.’”
Bill McKibben, Eaarth, pg. 168.
