There is a previous entry which is related to Oceans per se. However, given the number of problems facing our Oceans today, here are some links that help identify and work with issues related to the ocean. It is not only important to make ourselves aware of the problems, but also our children as well as try and come up with small changes we can make at our end.
1. One World Ocean: If you heard Sylvia Earle's award winning TED talk, this is her organization.
2. Mission Blue
3. Conservation for Oceans Foundation
4. Blue Legacy
5. Sea Save
