You must be very very very far away from the situation. The issue is an over population of the crocs who have been protected by the environmentalists.
I don't blame mosquitoes. I just swat them.
If you let them, they will come. At some point, you have to manage predator populations, too. Parts of the US are well aware of this, other parts, in the land of the paved sidewalk, not so much so.
We are part of the ecological landscape, and that does not imply that we have to make contributions to other animals in the food chain.
Don't let Agenda 21 thinking (it's a UN--global--thing) influence you, there are plenty of places where these critters exist, but sooner or later, you have to keep them out of your back yard.
