Any Astronaut Can Tell You You've Got

I Am Driven By What I Know; That The World I Love Is In Trouble.

The Arctic Is A Place That Historically, During All Preceding Human History, Has Largely Been An Icy Realm With An Impact On Ocean Currents. That, In Turn, Influences The Temperature Of The Planet. The Arctic Is Now Vulnerable Because Of The Excess Carbon Dioxide In The Atmosphere, With A Rate Of Melting That Is Stunning.

Since I Began Exploring The Ocean In The 1950s, 90 Percent Of The Big Fish Have Been Stripped Away. Tuna, Sharks, Swordfish, Cod, Halibut, You Name It, The Numbers Have Just Collapsed. Also, About Half Of The Coral Reefs Are Gone, Globally, From Where They Were Just A Few Decades Ago.

There Is A Terribly Terrestrial Mindset About What We Need To Do To Take Care Of The Planet-as If The Ocean Somehow Doesn't Matter Or Is So Big, So Vast That It Can Take Care Of Itself, Or That There Is Nothing That We Could Possibly Do That We Could Harm The Ocean...we Are Learning Otherwise.

I'm Not Against Extracting A Modest Amount Of Wildlife Out Of The Ocean For Human Consumption, But I Am Really Concerned About The Large-scale Industrial Fishing That Engages In Destructive Practices Like Trawling And Longlining.
