Melissa McGinnis is in Dana Point, California with eco expert Anthony Zolezzii who just wrapped up the Fortune Green conference. Zolessi thinks the most profound thing he has learned during the conference is that 50% of our oxygen comes from the ocean. People don't put the ocean up front like they do for rainforests, or carbon, or greenhouse gasses. People have to be really, really sensitive on how we look at water in the future.
