Answer 5

A couple of years ago I was in New Zealand.  There was a HUGE problem there with the imported Australian possum.  The possum was out competing small native animals as well as causing damage to native plant species.  The Oz possums were so prevalent, there was hardly a rual road where their carcases were not littered about after being run over by traffic

Answer 6

Look up Zebra Mussels in the Great Lakes. They are a non-native  species that has caused all sorts of problems. There is a lot of info posted on the net.

Answer 7

Do a search on Kudzu.  

This is a non-native vine that was INTENTIONALLY introduced to the south-eastern US for some reason.  It has effectively taken over the SE united states and is now impossible to irradicate.

Good luck.  (And your English is fine.)
