The deeper problem is monoculture versus multiculture (if that is the correct word). Our farming is currently focused on monoculture: only one kind of crop on a large field. Mainly because its efficient in maintenance and picking because it makes all kinds of mechanization possible. But monoculture is not good for the soil and bad for health of the crop. Therefore pesticides and fertilizers are needed. An alternative could be multiculture. Like for example http://jinjaritual.com/syntropic-farming/ http://jinjaritual.com/syntropic-farming/ A very divers pallet of fruits and crops in the same area. The soil will only get better and the plants protect each other. Just as in the 'real nature' ;-) The downside is losing the efficiency: getting all the different fruits and crops from the field is more labour intense. But the general maintenance will be much cheaper (no pesticides and fertilizers). And the yield will be healthier and probably more nutritious. The other downside is more commercial: the big companies that sell mechanized stuff, pesticides and fertilizers will always educate farmers into monoculture. But especially for more poor countries (or poor farmers !) a multiculture would be much more beneficial...
