The Red List reveals that deep-sea mining threatens the molluscs which hold promise for science.

The world's largest conservation organization warned that deep-sea mining is threatening to exterminate half of the molluscs species clustered around underwater vents. These molluscs have?promising? potential for medicine and technology.

IUCN (International Union for Conservation of Nature) reiterated its call for a ban on these operations in advance of the U.N. led talks that will take place this month. Growing numbers of companies are extracting 'critical minerals, such as copper or cobalt, from superheated fluids released by natural hydrothermal vents on the ocean floor.

Although these species make up less than 1% the global biodiversity of molluscs, they play an important role in the food webs at deep-sea vents.

According to IUCN’s "Red List", 62% of vent dwelling mollusc species--125 of 201 -- are now classified as being at risk of extinction because of mining operations that create sediment blankets which disrupt ecosystems.

Dr Chong Chong, a Mollusc Specialist Group member at the IUCN, said that deep-sea mines would destroy the ecosystem. He explained that the loss or molluscs in a vent field would mean the death of other vent species.

Chen stated that some vent molluscs had already proved to be valuable for the human society. For example, a scaly foot snail has developed a process of biomineralisation that helps researchers create nanoparticles that are used in new technologies like solar cells. Other vent molluscs are being studied in order to develop alternative materials to plastics.

He added that allowing these species to go extinct would mean losing biological solutions for future challenges in medicine and materials.

The Red List has been?released in advance of a U.N. meeting on the International Seabed Authority, which will be held from July 13 to 31 in Jamaica to discuss how to'regulate' metals extractions from the ocean floor. Like other environmental groups IUCN?has called for these activities to banned. However, many governments have the opposite view. The U.S. administration of President Donald Trump has expedited permits for U.S. firms searching for minerals in international waters.
