UNITED NATIONS: Governments will soon likely be able to apply for deep sea mining contracts in international waters, a plunge into the unknown that is worrying conservationists as calls for a moratorium on such digging grow. "I think it's a very real possibility that we see an application submitted this year," Emma Wilson of the Deep Sea Conservation Coalition told AFP. It is responsible for protecting the seabed in the high seas as well as regulating activities related to coveted minerals. The Nauru authorities have given assurances that they will not act immediately, but other companies sponsoring states' underwater mining ventures could take advantage of the opportunity, experts say. NGOs and scientists say that deep sea mining could destroy habitats and species that may still be unknown but are potentially vital to ecosystems.
