Especially as recreational divers and snorkellers, we must become aware of the impacts our activities can have on sensitive ecosystems. In order to preserve coral reef health and prevent further reef destruction, we all need to have a background understanding of one of the most diverse ecosystems in the world. My presentation will serve as a briefing/environmental education talk to help us miminize our impacts on the reefs while we are checking out this great place, San Salvador, the Bahamas!

Resources: I have a fairly long list of resources since I did a similar research paper for IES 531: Principles and Applications of Environmental Science (Dr. Greenberg). However, since it's been a while since I last reviewed them, I am listing only a few. There will be more to come anyway. . .

In addition, if you're interested, the NOAA website contains lots of cool stuff. The address for that is: http://www.NOAA.org
Also, http://www.florida-keys.fl.us/ntmarine.htm is a neat place to go to get more information on marine environmental education.
That's all for now!
