There ARE a number of very serious invasive species that threaten entire regions of wildlife.
Asian carp are going to destroy our rivers, especially if they continue their march to the great lakes and the mississippi. The common carp isn't good to have either, but their presence isn't 1/10th as bad as what happens as soon as asian carp move in.
The problem is that this species will not be affected at all by the passing of this bill. People are already aware of the problem, there are already actions and legislation at the state level controlling them, and they are already established in our waters.
One of the problems I have with this bill is that it really isn't going to protect native US land and wildlife from invasive species like it intends to.
