Heidi M. Sosik : The discoveries awaiting us in the ocean's twilight zone

The discoveries awaiting us in the ocean's twilight zone  (transcript)
Summary
This is a sad story that we can't save ocean life if we continue fishing and five countries must understand that, but they don't do anything.
Why?
Five countries are China, Taiwan, Japan, Korea, and Spain which alone account for almost 80 percent of the fishing in the high seas. They wouldn't think that not only they lose their jobs if they stop fishing now but also they'll lose their jobs if they continue fishing like that.
I guess that just they must have their own way.

If we stop fishing industries, we can see pristine high seas in only 10 years 1) and fishermen and its countries will make much more money from tourism. 2)
Of course, forests are important to clean our air. The ocean also gives us more than half of the oxygen we breathe. It absorbs much of the carbon pollution that we throw in the atmosphere.  3) In fact, for fishing industries in high seas, huge government subsidies are used. It's more than the profits. 4) The high seas catch does not contribute to global food security because of upscale. 5)

Why do we continue those?  What goals do fishing industries have? Is it important to hire or to be hired there?
The speaker tells us that this is the type of cooperation and willingness to set aside differences that we are going to need.
We are people who kill or protect our oceans, aren't we?
