Scientists Urge Caution On Underwater Mining

Leave a comment

For years the ‘bad ones’ have poisoned rivers, devastated forests and displaced communities, and now massive companies are rushing to dig up the seabed for precious metals.

MIT: “The ocean’s deep-sea bed is scattered with ancient, potato-sized rocks called “polymetallic nodules” that contain nickel and cobalt — minerals that are in high demand for the manufacturing of batteries, such as for powering electric vehicles and storing renewable energy, and in response to factors such as increasing urbanization. The deep ocean contains vast quantities of mineral-laden nodules, but the impact of mining the ocean floor is both unknown and highly contested.”

And yet, only twenty-four people have the regulatory powers to stop this type of plunder in our planet’s most fragile places:  The International Seabed Authority.  You’ve likely never heard of them because this group attracts as little attention as an underwater mine miles offshore.

A few countries have agreed to full or partial bans, and leading scientists have appealed for a freeze on deep sea mining contracts.

Mining companies claim they can mine the seabed safely, but authorities in Namibia, Australia and New Zealand have blocked seabed mining projects.  Scientists point out that many deep water species are being discovered quite regularly, and that the ocean floor can take decades to recover from disturbances such as the creation of sediment plumes from deep sea floor bed mining.

There are limits to how deep Surface ships can reach- but is that enough to protect the deep of our Oceans?
There are technological limits to how deep Surface ships can reach- but is that enough to protect the deep of our Oceans? New technologies and techniques always lead to deeper mining.

The International Seabed Authority has already issued licenses for exploratory mining across 1.2 million square kilometers of ocean floor. As mentioned earlier, this regulatory body is almost unknown, and its 24-person Legal and Technical Committee is solely responsible for the detailed scrutiny of proposals and environmental safeguards.

Fined $2K For Possessing Living Snakehead “Frankenfish”

2 Comments
Frankenfish- the other name for the Snakehead. Frankenfish usually refer to genetically modified fish (search genetically modified salmon for more) but due to the 2004 movie "Frankenfish" which starred a Snakehead- this term is being used more and more for The northern snakehead, (Channa argus). This invasive species is now being discovered throughout North America and the United Kingdom. CP

A Chatham man has been fined $2,000 for illegal possession of snakehead fish. Yung-Chieh Liu pleaded guilty to illegally possessing live invasive fish. In addition to the fine, two snakehead fish were also forfeited to the Crown.

Justice of the Peace Malcolm Rogers heard the case in the Ontario Court of Justice, Blenheim, on April 17, 2013.

The Ministry of Natural Resources reminds residents that it is against the law to have certain invasive species in your possession, because they pose a serious threat to native species and ecosystems. 

“The Northern Snakehead might enjoy life in Canada, but it would not be welcome here. This fish, native to eastern Asia, has invaded parts of the United States, where it threatens to disrupt ecosystems and native fish species unaccustomed to its presence. Scientists at Fisheries and Oceans Canada (DFO) want to stop the snakehead from establishing a base in Canadian waters – and building a strong defence is the key to success.

The risk posed by snakeheads is very real. Several of the 36 species have a long history of invasions, and are very hardy. They can even live out of the water for a time – to pursue their prey or find a new home if the former one dries up. They survive winter under the ice of northern lakes; some have even recovered from being frozen! The Northern Snakehead, in particular, thrives on conditions that are similar to many Canadian waters. It is a voracious predator, and it grows rapidly to an adult length of 1.5 metres or more.

In their native waters, some snakehead species are fished for food or used for aquaculture. Many are exported to other countries where they may be sold live in food markets and pet shops. Scientists believe that the Northern Snakeheads found in lakes in some US cities may have originated from food markets. Some may have been released to the wild in an ill-advised attempt at fish stocking or because they were no longer wanted as pets.” Department of Fisheries and Oceans Canada

Be on the lookout for the Snakehead. Report any sightings and help keep this invader out of Ontario's waters.
