Bottom line is this:
-the earth is warming and regardless of what we do now, it will keep warming...too late...sorry. We should work hard to not add to it anymore but we have passed the point where we can stop it.
-the oceans are increasing in acidity. As with above, it is happening and we are too late to stop it. Lets not add to it.
-the fish are and marine mammals are disappearing at an alarming rate. Unlike above, there is a LOT we can to about it. We can actually change and let fish and marine mammal stocks start rebounding.
We will need all the species numbers we can muster to survive the impacts of global warming. That means focusing on increasing (not just slowing the decline) of marine stocks. So often today, global warming is used as a catch all for ignoring other environmental concerns. Recently I read about the fisheries minister of Philippines blaming plummeting tuna stocks on global warming. What total BS! They have been overfishing their tuna stocks for years and watch groups have been warning of the impending crash. Now that the crash is happening, they blame global warming. In effect, they are removing all blame and policy implications.
I just heard from a friend today who had spoken to his buddy in spain. This person had spent a day at the largest fishing port and spoke with many shark fisherman. Every day they are bringing in THOUSANDS of sharks. Sadly today, almost none are longer than 1 meter. In addition, they must travel thousands of miles to catch these juvenile and infant sharks. They have litterly wiped out the atlantic shark populations off Europe.
Yet what is the EU's response this situation. NOTHING but useless debate and ongoing "ANALYSIS" of the situation. We analyze and debate until its all but gone. Then we protect that last stragglers in once flourishing populations.
Global Warming and Ocean Acidification are a fact that we and the ocean's marine creatures are going to have to deal with. We should not contribute more to this.
But: We need drastic and immediate change in global fisheries. This is something we can affect TODAY if we (read anyone who cares) are willing to make the sacrifices and drive for change.
Can we make a difference? I admit the outlook is completely dismal. But, we must try and keep trying.
