It is common knowledge that conventional farming contributes a lot to climate change. Lesser pollution due to fertilizers, significantly decreased emission of greenhouse gases and reduced transportation of ingredients, packaging and food, indicate that localised sustainable food systems should be the farming of the future instead of exporting our mistakes to developing countries in Latin America or Africa, too.
But it was often claimed that organic farming cannot yield as much food as conventional farming, thus it is no feasible alternative if we want to feed the world.

But that’s not true: researchers from the University of Michigan found that it is possible to yield by organic farming almost as much food as conventional farming in developed countries and up to three times as much food as conventional farming in developing countries can.
