> Mess with the ecosystem in an extreme way and you might suffer dire consequences. This was exactly my main point. Apparently the elimination of sparrows also led to a dramatic increase in mosquitos (since sparrows eat mosquitoes), so it had a domino effect of negative impacts. They didn't have the technology to obliterate mosquitoes at the time, and that's essentially what we're talking about here...so I'm saying there will likely be unforeseen consequences if people mess with this. (coming from a guy who hates mosquitoes - i actually bought mosquito pants last year bc they are so bad in the summer when I'm doing yard work)
