And that's precisely why I have reason to be optimistic.
If you are, er, "experienced" (translate that to "older") you remember how rapidly the rain forests were once being destroyed, and the frightening part was that no one really knew that much about what was going on. Then, in the late 70's and 80's, there were several popular movies that highlighted the situation and popularized it. One was Medicine Man, with Sean Connery. Another was Emerald Forest, and on the kid's front there was Ferngulley. These movies and a number of documentaries and TV programs brought the problem to the forefront and soon organizations began to spring up in order to save the forests or at least slow down the rate of their destruction.
That is what I see is needed for the health of our oceans. As divers, we simply must be proactive in bringing the ocean's causes to the attention of everyone, especially those who do not live near the sea. Only when more people are ready to get involved will we see real change begin to occur. That's why I volunteer time to be a spokesperson for the national marine sanctuaries in an area that is pretty landlocked. Hopefully, we'll begin to make a difference.
