Marine Issues

The following is an excerpt from Dr Sylvia Earle’s book, ‘The World is Blue’:

Consider:

- Since the middle of the 20th century, hundreds of millions of tons of ocean wildlife have been removed from the sea, while hundreds of millions of tons of wastes have been poured into it.

- 90% of many once common fish have been extracted since the 1950’s; 95% of some species, including blue fin tuna, Atlantic Cod, American Eel and some sharks have been killed. And taking of them is still allowed.

- Destructive fishing techniques- trawls, longlines, rock-hopping dredges- not only continue to take too much, they have destroyed habitats and killed millions of tons of animals that are simply discarded. Every year, industrial fishing wantonly kills hundreds of thousands of marine mammals, sea birds and sea turtles, and hundreds of millions of fish and invertebrate animals.

- Half of the shallow coral reefs globally are gone or are in a serious state of decline since the 1950’s; in much of the Caribbean, 80% are dead.

- Deep coral reefs are being destroyed by new deep trawling technologies aimed at capturing fish that are decades, even centuries, old. The destroyed corals are thousands of years old.

- More than 400 ‘dead zones’ have formed in coastal areas in recent decades, and the number is increasing and accelerating, reflecting changes in ocean chemistry.

- Global warming and other changes in climate are affecting ocean systems and ocean life just as on land, and those impacts in turn are influencing the atmosphere and terrestrial systems. As the principal driver of planetary climate and weather, changes in the ocean resonate globally.

- The ocean’s pH- the measure of alkalinity or acidity- is changing owing to increades CO2 that in turn becomes carbonic acid. Consequences are likely to be most obvious for coral reefs, molluscs, and plankton housed in carbonate shells, but the changes touch all forms of life in the sea.

- Most troubling, perhaps, is the profound, widespread ignorance about the ocean and it’s vital importance to everyone, everywhere, all the time. It is not just the fact that less than 5% of the ocean has been seen, let alone explored. Even what is known to scientists is not widely appreciated by the public, and certainly not by policymaking officials.

Please watch the videos below- first, a speech by Dr. Sylvia Earle on the state of our oceans, one of the most inspiring and eye-opening speeches on marine conservation I have ever seen and second, Paul Watson outlining why our world should be known as ‘Planet Ocean’… why is it important to save marine biodiversity?

 

 

 

Keep coming back to this site as I will continue to update it with links and places you can go to help our oceans!
On the path to protect,

  1. I would give my life to make EVERYONE aware of our Beautiful Oceans that are beyond destroyed, faster than a rapid wildfire vs dry sage brush! WAKE UP WORLD!!! Our Oceans Die, We die! *love* 4 Sea Shepherd, All Activists & Ocean Lovers! ;)
