Several countries have already been affected by plans for Deep Sea Mining, and hence developed resistance and information fronts along with their inhabitants. Papua New Guinea has been a testing ground for experimental mining promoted by Nautilus Minerals – that has future plans in the Fiji, Tonga, Vanuatu, and Solomon Islands – and has seen the development of resistance movements to halt the advance of exploration. In Papua New Guinea, the Solwara Warriors, Bismarck Ramu Group, PNG Group Against Seabed Experimental Mining (PNGGASEM), Papua New Guinea Mine Watch, and ACT NOW PNG, are some of the active resistance groups. It is important to expand the network of informed solidarity and to cross resources of the campaigns and movements that are being developed to strengthen our positions.
In Portugal, Quercus, Liga para a Protecção da Natureza(LPN), Sciaena, Grupo de Estudos de Ordenamento do Território e Ambient (Geota) are agaisnt deep sea mining. Their position is supported by 39 other international NGOs, which at the UN Oceans Conference in New York, USA on June 9th 2017, through spokesperson Monica Verbeek, executive director of Seas At Risk, warned the international community that "Deep sea mining is not necessary in a world that is committed to sustainable production and consumption under Agenda 2030. Unless we stop to reflect we risk ruining one of our ecosystems most valuable asset that plays a vital role in the health of our planet, for an obsolete dream of unlimited growth. "
