Biosphere

The biosphere is the ecosystem linking all other ecosystems on the planet. This layer includes millions of species of animals, plants, and microbes found in every nook and cranny of the land, oceans, and air. Microbes have been found 40 kilometers high in the atmosphere, more than 5 km beneath Earth's crust, and 10 km below the sea. The fate of all living things in the biosphere hangs on the actions of a single species, Homo sapiens. We humans. Planet Diary tracks the health of the biosphere and efforts to protect it.
