Habitat loss is probably the leading cause of decline and extinction right now. I'd wager habitat loss due to agriculture is killing more than glyphosate runoff by a significant margin. Whether the degree to which habitat loss is averted with space-efficient GMOs is sufficient to offset glyphosate runoff, I cannot say. I suspect the most ethical option is to stop consuming food grown in particularly threatened environments, particularly imported tropical fruits, whether or not they're organic.

Regardless, it seems clear to me the matter of organic vs non-organic is not as clear cut as the organic industry and their prolific passionate proponents would have us believe.
