While organic production avoids synthetics, it introduces other hazards to our health and environment. Organic producers use 'naturally' derived substances such as copper sulfate and pyrethrum, which are just as toxic and carcinogenic as many conventional chemistries.
Organic cultural practices require tillage and the use of manures, which both contribute to erosion and pollution. Organic production also can have yields as low as 10-40% less than conventional methods. Thus feeding the world via organic methods would require more land i.e. destruction of habitat and biodiversity.
