Low Doses of Common pesticides damage birds

[Catherine]

University of Saskatchewan Biologists have been studying the effects of low doses of neonicotinoids and organophosphates on birds. It is known that larger doses are fatal. It seems that low doses are serious as well. They cause things like weight loss and disorientation, the inability to find  north. For migrating birds this would be fatal.

I don't like the fact that they experimented on live birds, but the information is still very important.

We already know that these pesticides are killing our bees. Now we know they are destroying our birds. 
We have put these pesticides into the food chain so who knows what else is being effected.
What happens to a hawk that eats a dying song bird? We went through this with DDT and we wisely banned it. Why are we even using these chemicals at all when we know how toxic they are.

Something we should be considering is the fact that we have put these chemicals into the food chain and they are toxic and we are part of that food chain. What effect will they have on humans who ingest them? By the time we know it will be too late for the people who have been exposed. We don't seem to learn for all that we are an intelligent species.
