With the global population now well over seven billion people there are few remaining parts of the world relatively untouched by human activity. We assess the current state and future prospects of five final frontiers: rainforests, Antarctica, the Arctic, the deep sea and space.
The deep sea is truly the last frontier on our planet. With an average depth of more than 4,000m and falling to almost 11km in the Marianas Trench (put Mt Everest at the bottom of this trench and its tip would be more than 2km below the ocean’s surface). This is an environment that is quite unlike any in human experience, and few have experienced it first hand.
