s land-based minerals become depleted and prices rise, the search for new sources of supply is turning to the sea floor. This emerging industry, facilitated by advances in technology, poses a major threat to our oceans, which are already suffering from a number of pressures including overfishing, pollution, and the effects of climate change.
The remote deep and open oceans host a major part of the world’s biodiversity, and are vital for our survival on Earth. The deep sea plays an important role in regulating planetary processes, including regulation of temperature and greenhouse gases. It supports ocean life by cycling nutrients and providing habitat for a staggering array of species.
Deep seabed mining could have serious impacts on the ocean environment and the future livelihoods and wellbeing of coastal communities. Only 3% of the oceans are protected and less than 1% of the high seas, making them some of the least protected places on Earth. The emerging threat of seabed mining is an urgent wake-up call.
