'Alien' plants

The Los Angeles Times ran a long story on fighting alien, non-native 'weeds.' I sent this note in response (not published):

I'm always surprised that so many people who welcome immigrant people reject immigrant plants, calling them non-native and alien and trying to wipe them out. Why? Yes, they will alter the environment, just as immigrant people do. 

If they thrive here, I welcome them, both people and plants.
