This animation shows the global vegetation cycle. Equatorial regions (particularly Earth's two largest rainforests) stay green all year round. The Northern and Southern parts of Earth's landmasses vary seasonally, going from virtually nothing in winter to a lush green in summer. Due to the positioning of Earth's continents, the Northern hemisphere shows much more variation.

This swirling shape in the sea, off the coast of Iceland, is a bloom of phytoplankton. They usually happen when water from the deep sea is dredged up to the surface, where there's enough light to support photosynthesis.
Phytoplankton are a major part of Earth's carbon cycle, accounting for about half of all photosynthesis on the planet.

And this is Earth, as seen from Saturn, 1.44 billion kilometres away. Taken on July 19, 2013. So technically, this one photograph contains every human who's ever lived. Right there on that little blue fleck of light.
Earth is tiny. We should really take better care of it.
@InvaderXan Sorry, I don't get it. How can this photo contain every human who's ever lived? Saturn and Earth are only some light hours apart, so people who died several years ago cannot be on this photo. Secondly, we can only see the side facing Saturn, i.e. roughly one half of it's population.
