Debate about disposal

The impact of pesticides on water quality in organic systems has rarely been studied (Stock-dale et al. 2001). Again, however, most of the water contamination comes from herbicides used in conventional farming. There is some debate about the disposal of sheep dip and the relative risks of pyrethroids versus organophosphates. Organic farmers only use the former and they are potentially more damaging to aquatic habitats. 

Disposal of plastics has been the subject of considerable debate as municipalities face increasing problems in locating sufficient landfill space. The number-one waste is paper products, which make up about 40% of the volume in landfills. (Newspaper alone accounts for 16% of the volume.) Next is plastics, which make up about 20% of the volume in landfills.
