There could be an undiscovered species on Earth unlike anything we’ve ever known. Not in the ocean, but the ocean itself! Its body spans thousands of miles; its heart beats with a one-thousand-year pulse. It could even have an immune system capable of annihilating all other life on earth. Just as our bodies function through the interaction of water with individual cells, including bacteria and other microorganisms, the ocean’s residents might collectively form a super-organism. A recent discovery suggests the ocean is a living being capable of thought. If so, what is the ocean thinking about us?

At a time when the Earth’s surface is changing faster than ever in human history, watch cities grow, forest disappear and glaciers melt.
In the ever-growing grey of cities one man is feeding thousands of parakeets; in Sumatra a female orang-utan and her daughter face life in a forest under threat; while in Tanzania local people use satellites to replant a forest, securing the future for a family of chimpanzees. This is our home as we’ve never seen it before.

So he unleashed the power of the mob upon the streets of Rome, with devastating consequences.
