I agree with Senator True Democrat, life in prison for four offenses relating to endangered animals is outrageous, as is the $500k fine for the first offense. Kill one plant from a species that's endangered and pay half a million? That's overkill (pun intended).
Personally, I think that it's a good idea, but it could use refinement... for example, we should have to make it required to prove that the person knew that it was endangered and still killed it, as well as tweaking the punishment to be a little bit more reasonable.
