Will Fish Become Extinct Species in 100 Years?

Thanks to superior human activity, wildlife on land is almost extinct and the next in line is the marine life, mainly fish and the time period researchers have set is just 100 years.

A consortium of researchers said wildlife in the oceans is as healthy as it was on the land hundreds of thousands of years ago but it may change in the next 100 years due to some major challenges to marine life.

“A lot has changed in the last 200 years. Our tackle box has industrialised,” said lead author Douglas McCauley, professor at University of California – Santa Barbara. The main culprits will be the factory farms in the sea and cattle-ranch-style feed lots for tuna.

fishShrimp farms are eating up mangroves with an appetite akin to that of terrestrial farming which consumed native prairies and forests.

“Stakes for seafloor mining claims are being pursued with gold-rush-like fervour and 300-ton ocean mining machines and 750-foot fishing boats are now rolling off the assembly line to do this work,” said co-author Steve Palumbi from Stanford University.

The researchers attribute it to the increasing industrial use of the oceans and the globalisation of ocean exploitation that will damage the aquatic life and hit the health of marine wildlife, making the situation in the oceans as grim as that on land.

McCauley also points out, “We now fish with helicopters, satellite-guided super trawlers and long lines that can stretch from New York to Philadelphia.”

“All signs indicate that we may be initiating a marine industrial revolution. We are setting ourselves up in the oceans to replay the process of wildlife Armageddon that we engineered on land,” he warned.

Apart from humans, the next serious threat to ocean wildlife is climate change, which, according to the scientists, is degrading marine wildlife habitats and has a greater impact on these animals than it does on terrestrial fauna. The findings have been published in the journal Science.
