For decades, large corporations have poisoned rivers, devastated forests, and displaced communities. Now, they’re rushing to mine minerals from the last untouched frontier on the planet — the deep sea.
The deep sea may be vast and unexplored, but it is incredibly important. It encompasses 95% of the ocean’s volume and is the largest and least explored of Earth’s ecosystems. Some scientists believe that the deep sea and its water column may be the largest carbon sink on Earth, and new species are still being found there.
