I'd like to point your attention to Mission Blue and the new Mission Blue movie. Mission Blue was started by the renowned Dr. Sylvia Earle, and whatever your view on environmental stewardship, it's good to be aware of the differing opinions and efforts impacting marine ecology. To pull directly from the organization's website:
"Mission Blue is a global initiative of the Sylvia Earle Alliance, a 501c3 organization, which was formed in response to Sylvia Earle’s 2009 TED Prize wish. Dr. Earle urged people “to use all means at your disposal — films, expeditions, the web, new submarines — to create a campaign to ignite public support for a global network of marine protected areas; Hope Spots large enough to save and restore the blue heart of the planet.”
Currently, the Mission Blue community includes 50+ respected ocean conservation groups and like-minded organizations — from large multinational companies down to individual scientific teams doing important research."
