Wednesday at Downpour (Bible Study) we were talking about how people can be an influence, for good or for bad, on those around them. And in the discussion we started to get into how this works in nature.
Well, I happened across this (http://www.invasivespecies.gov/). Check it out if you have the time, it's a list of species that were taken out of their natural elements and now are causing havoc in their new home (even here in Indiana we have a few, they are listed on the site).
Enjoy, something to think about...
