Disturbance but countries including germany, france, spain and chile have all called for a pause or ban on deep sea mining. campaigners have released videos of exploratory mining spelling waste water full of sediment onto the ocean surface, alleging it has the potential to smother ocean life. the upcoming deadline for a decision was set by the tiny pacific islanders of nauru. in 2021, nauru gave notice that a company under their sponsorship intended to apply for mining approval and it triggered a clause giving authorities two years to set regulations for the practise, a deadline which expires on sunday. clearly we won t be able to have an agreement on a final tax for exploitation until sunday, now. so from monday onwards and for two weeks we are going to have the next council meeting at the international seabed authority where these member states will get together and among other topics also discuss what is going ....

Into the environment, they can be taken up by organisms, they can be trophically transferred from one part of the food web to the other, and they can be bio accumulated, hence our concern about it. and so we re not dealing with a blank canvas here. the ocean is already affected by lots of stressors, as are the people who depend on the ocean the fishers, the people of the pacific, and particularly the islanders who depend on the ocean for their food, for their culture, for their ecology. what we see is a situation where major questions remain on whether or not the radionuclide, not just tritium, tritium is a concern because of the way in which it interacts with other organic materials and organisms as well. but there is a suite of others caesium, strontium, cobalt, ruthenium 106. we ve seen an inadequate radiological ecological impact assessment that makes us very concerned that not only willjapan be unable to detect what s getting into the water, the sediment and the organisms, but w ....
