The oceans are unable to renew what we’re consuming fast enough. With growing population demand, paired with boats that are essentially floating factories – as they can stay out at sea longer than before, catch and process the fish – and you have overfishing!
Because the size of catch has been dwindling over the years, fishing fleets have resulted to indiscriminately casting out bigger nets..
For every 1 ton of prawns caught, 3 tons of little fish are caught in the nets and thrown away.
The throwaway fish is called Bycatch; the unwanted fish and other marine creatures trapped by commercial fishing nets during fishing for a different species.
- 650,000/year Whales, Dolphins and Seals were killed around the world as a result of bycatch
- 50 Belugas Whales killed from bycatch annually
- Only 40 species of plankton exist anymore which further effects marine life that eats it
Disappearance of Predators
It’s taken only 55 years to wipe out 90% of the ocean’s predators, causing disruption of the marine ecosystem. Species of whales, sharks, tuna, mackerel, dolphins and marlin are rapidly disappearing or have already gone. After the big fish, commercial fishermen can seemingly go down the food chain, until everything is depleted.
The aquatic equivalent of deforestation. Boats cast huge and heavy nets that are held open by heavy doors weighing several tons each and drag them across the ocean floor. Because we cannot see it, we must imagine the devastation that causes.
Destruction of Habitat
Coral Reefs which are home to 25% of all marine life are being destroyed. The reefs grow at a rate of 0.3 cm to 10 cm a day. The reefs we know of have been growing for the last 5,000 to 10,000 years.
This is a new word in our vocabulary and dictionaries. The Cambridge Dictionary meaning for it is – destruction of the natural environment of an area, or very great damage to it. Over-fishing is tantamount to ecocide.
“The number of overfished stocks globally has tripled in half a century and today fully one-third of the world’s assessed fisheries are currently pushed beyond their biological limits” according to the Food and Agriculture Organization of the United Nations.
Whatever preferred diet we might hold, we cannot ignore the responsibility that goes with our choices, particularly when there are alternative solutions.
“All of us have in our veins the exact same percentage of salt in our blood that exists in the ocean, and, therefore we have salt in our blood, in our sweat, in our tears. We are tied to the ocean. And when we go back to the sea – whether it is to sail or to watch it – we are going back from whence we came.” John F. Kennedy
We must focus on sustainable and sensible alternatives to allow nature to clean up our mess.
