Here's an idea most biologists will hate

My sister is a biologist. She has ranted on and off about invasive species and such similar things. I thought of that when I found this article. Big Game Imports to summarize, some researchers think that it would be a good idea to introduce many animals from the african savannahs to the great plains of the US. Why you ask? Because they think these animals could fill the ecological spots formerly filled by mamoths, sabertooth tigers, and similar extinct creatures, and provide a new enviroment for the endagered species of Africa. A further benefit would be to provide an increase in tourism to the currently economicaly depressed areas of the great plains. Of course one can expect ranchers and farmers to be a tad leery of releasing lions and elephants to roam the plains. Interesting idea but I see issues.....
