I have another question, and it's a bit philosophical. What I'm hearing from you folks is that the logical and common sense approach is to make sure that we utilize the best practices that we already know about for prevention, which I think is what we're trying to do, and to make sure that we have the funding available in order to implement those best practices with regard to prevention. I suppose it's a bit of a philosophical conundrum that something that will play out for years and decades to come is whether or not we can stabilize the effects of climate change.
Given the fact that the world is changing, which would infer that the natural ranges of species would also change, how will we differentiate in terms of what is invasive? Right now, some people would say that an invasive species is a species that is moving into a geographic range that it didn't once occupy, although because of certain conditions changing, it is now part of the natural range. How much effort should we place on differentiating between species that are undergoing a natural extension or change to their natural geographic range and those that are truly invasive and wouldn't otherwise be there, other than because of some man-made type of vector transmitting them there? Is that a conversation we need to have?
