un-ethical eco-tourism marketing

I am currently researching a project to highlight both good and bad examples of tourism companies offering an eco-friendly product or destination. I have had no problem finding good examples with referances to prove their advertising is correct. Finding bad examples seems to be lees fruitful. I may be looking in the wrong places but if you know of any web sites or actual company names I would be grateful for your assistance with my studies.

Thanks again.
