Tourism Pollution

I found an article about Tourism Pollution, and in it I found a small blurb about Venice. It provided estimates and information on how tourism is polluting Venice, and how the tourism is driving away local Venetians.

Oceana

Oceana is a non-profit organization that tries to preserve ocean waters. They conducted experiments on Cruise ships and came up with data on how cruise ships contaminate waters. I think this organization's data may prove helpful when it comes to the environmental aspect of our project.
Loose environmental requirements allow cruise ships to dump everything overboard except untreated and solid waste. Surely the numbers on fuel consumption, and waste production will be useful in our analysis. Although this organization doesn't pinpoint any specific areas, they give us a general idea of how harmful ships are.
