This is quite an intriguing question. What seven places should be the Seven Wonders of the World? I think you have the idea of what I am talking about. I need your help to give me seven places that should be protected and should not be contaminated, destroyed, changed,etc. by tourists. Don't forget it that it won't be easy. After giving me seven places. You need to type the reason/reasons on why the place should be protected. Put your reason next to the place. The person with the best answer will be the winner and will win the most points.That's it! And also remember this question is not just about Polls and Surveys, this is about protecting our world and making it a better place to live.

4. Hawaii, Sydney, Tokyo, Florence, San Francisco, Bangkok, and Kuala Lumpur. They're all wonderful places if you love cities and people.
5. Since this is the Conservation forum, I would pick Madagascar to head the list, with all its endemics, many of them endangered. For a similar reason, peninsular Florida is worth saving. So are Tasmania and New Zealand. To get the last three, I'd have to dig out my Biogeography notes and I'm too lazy to do that at the moment.
6. Iraq ! mines !
