The spread of “Black Rats”

A great article from Discovery Magazine “Man is the environment of the rat“

This story talks about the complexities of movement of invasive species from around the world, also discusses the spread of other problems associated with the spread of those animals and their pests. We have an issues with Mollusks hitching rides on boats and engines. They than drop off or multiply in other fresh bodies of water. Most cases are accidental but sometimes we our are own worse enemies. Bringing to mind Hawaii, bringing in Mongoose to control rats. Rats come out at night not Mongooses. Bad decision and bad consequences.  Now Hawaii has both and they can do some real damage to areas.
