Here on Earth is a biography of our planet and our species. We stand at a crossroads, where comprehension of our place in nature—of our true abilities and of our history—is supremely important. We have formed a global civilisation of unprecedented might, driven forward by the power of our minds—a civilisation which is transforming our Earth. We are masters of technology, and of comprehension, but it's what we believe that may, from now on, determine our fate.
