The price of saving our seas is in the hands of the consumer.
Major studies just out have documented a red flag for our marine environment. Marine biologists now estimate that the world's population of fish in the ocean is roughly 20% of what there was about 50 years ago. That's a drop of 80%!!!! They blame the fishing methods of the world's commercial fishing fleets, mostly the ones out of Japan that use the "drag net" method of fishing. The "drag net" simply lays on the bottom of the ocean floor and is dragged to fill it. Any and all sea life that is on the ocean floor is either crushed or scooped up. About 75% to 90% of the catch is not edible and has either died or dying and will be disposed of by throwing overboard or ? Japan is doing this because tuna is a prized fish needed for their sushi. The biologists at the Monterey Bay Aquarium estimate that the average tuna 200lb tuna is worth close to $100,000 on the Japanese sushi market.
The fishing methods have to be changed. This has to be done in order for the sea life to thrive before they are all extinct. There are several tuna fishing companies that now fish using the good old hook and bait method. Yes the price is higher for a can of albacore tuna but not by much. The consumer will have to change their buying habits in order to push the fishing industry to change it's ways. The most successful way to change something is to refuse to buy what is being offered - money talks. The great majority of the world's current problems were brought about by people trying to sell something to someone else, even if that something was bad for the environment.
