The eco system is changing. Plants don't seem to be affected all that much, at least not yet. The jury is really out as to whether or not this is going to alter ego systems for the worse. It needs to be monitored more closely ethically. If i'm happy to see worms in my garden, john, the reality is you're not canbule to get rid of them anyway. So you might as well be happy that they're there and just hope tat we don't reintroduce them to other places in the near future.
