Invasive species

We're watching an episode of The Dick Van Dyke Show. Rob is thinking about buying a nutria coat for Laura. "Nutria," I say, "that's an invasive species." Which it is. Fortunately Rob tells the furrier he wants 10 coats. That should get rid of a few.

What's an invasive species? Gosh, what isn't? Actually that website, The National Invasive Species Information Center, has a lot going for it. There are even smart phone apps you can download. That Project Noah app sounds cool.
Project Noah lets you take cell phone pictures of bugs and trees and then sends back an identification of the exact type in as little as 24 hours.
I don't even have a smart phone but I'd sure like that sort of identification access.
