Oh Yes - Mankind and his "wonderful" Motives.
Loads of people like Tuna - and will pay a lot of money for some types of Tuna.
There are SUPPOSED to be Controlling Quotas on Tuna Fishing - which the Scientist all agree would NOT be enough to prevent their Extinction.
However - the Fishing Consortiums of many Nations, particularly those in Japan, are almost openly exceeding these Quotes by a wide margin. Japanese Fishers ( and others ) are catching at least 400% of the permited Quotas.
But they are not being Eaten, most of them - they are all being put into MASSIVE Cold Stores.
The Japanese Fishing Consortiums ( and others ) KNOW that the Tuna will all be EXTINCT within Ten Years maximum. Then - Tuna Flesh will be like Gold Dust - some people, somewhere wil pay almost ANY PRICE to eat thawed Tuna Flesh.
The people who own the Cold Stores will only have to wait until they can sell Tuna for $30,000 per Kg, $300,000 per Kg, $3 Million per Kg, or whatever - because there will be NO OTHER TUNA ON EARTH AT ALL.
