A Perfect Planet

We can't control volcanoes, but without them there would be no life on Earth. They may appear destructive but magma from the planet’s molten core builds land and mineral rich ash from regular eruptions fertilize the surface.

From the frozen poles to the searing deserts, The Sun reveals how animals have come up with brilliant strategies and adaptations to survive the uneven amounts of sunlight that fall on our unique planet.

Weather controls the uneven, and often patchy, distribution of freshwater around our planet. In doing so, it shapes the lives of animals across the globe, giving rise to an incredible diversity of species and habitats.

There are not five, separate oceans, but one -- its waters linked by powerful forces that keep them forever on the move. This constant mixing around the planet is vital for the health of our ocean and for all marine life.

Humans are changing our planet so rapidly, it's affecting Earth’s life support systems: our weather, our oceans and the living world. We discover what is going wrong and how Earth's natural forces can provide a solution.
