Deep-sea mining 'must responsibly respect ecosystems'

RATE THIS! +26
Posted in Science on 19th Feb, 2014 03:11 AM by AlexMuller

The researchers said the oceans' lowest reaches had untold riches that could benefit mankind enormously, but not if the harvesting were done destructively. The scientists called for a "new stewardship" of the deep sea. This would require effective ecosystem management and sustainable methods of exploitation.

 
The researchers said the fishing sector had already initiated some very damaging practices, such as the widely criticised use of heavy-rolling, sea-floor nets, but that there was still time for other sectors to take more sensitive approaches.
 
This includes the imminent development and spread of industrial-scale deep-sea mining. The ocean floor is being targeted as a source for a range of metals and minerals. Part of this is driven by the insatiable appetite for modern technology devices like cell phones and hybrid cars.
 
The battery in a Toyota Prius hybrid car, for example, requires more than 10kg of lanthanum.
 
Large tracts of sea bed have now been licensed to permit the prospecting of manganese nodules, cobalt crusts, massive sulphides to produce copper and zinc, and even phosphates to make fertilisers. Some of these licences are certain to turn into full-mining permissions this decade.

Short term energy and economy needs can result in very shortsighted action - any deep see resources have to be managed with great care

Mining of the deep ocean has been talked about for about 50 years, it is now that the advance in underwater robotics and rising prices have brought this closer to reality. Reply

It should also be remembered that it is not cheap to work in the deep sea Reply

They state that "The deep ocean is a vast repository of resource" and that "we almost surely are going in there to mine" - this is the time to make sure that this done with care! Reply

In our town, in Nevada, (we also have a place on the Yellow Dog) we have new trucks, too. They are all blaekcd out, looked like armored vehicles, and the men in side are hidden by blaekcd out windows. This in a tiny little resort town next to Lake Tahoe. Soon, all the state vehicles will look like swat vehicles, intimidating all. Stay in line, don't say a word, shut up and do as you are told. Afterall, you might be classified as a terrorist. Patriot Act 2 and 3 are on the books, ready to further restrict the right to gather and protest. Let's make Eagle Rock COUNT!! Reply

Three years after the acqoisitiun, our platform and our business continue to grow and evolve. We are still committed to the same principles that informed the site early on, but we know things have changed. As bandwidth has increased, so has our video quality. Reply
