Zebra Mussels

I decided for the Lollybot 'Accidental' show to enter a piece about the introduction of zebra mussels into lake st claire and subsequently into all the great lakes in I think 1986. Zebra Mussels grow rapidly and cover other native clams, killing them. They also are bad for power plants and water systems clogging drain pipes and so on. The one good thing zebra mussels have is that they are excellent water purifiers, that's one reason why the great lakes have become much cleaner in the past 20 years, but the great lakes are supposed to be more murky water, and the natural species that should act as a filter are the marsh land grasses which people have destroyed for subdivisions and sprawl along the coastlines.



I don't think that shopping cart will be used anymore.
Where zebra mussels are now prevalent and intrusive.
Also I thought this picture was cute, explaining global warming in a lighter sense.
