A Perfect Planet
Humans are changing our planet so rapidly, it’s affecting Earth’s life support systems: our weather, our oceans and the living world.
How Earth's five oceans connect to form the largest ecosystem on the planet, and how its network of currents supports the health of the seas and marine wildlife.
How weather controls the distribution of freshwater on Earth, which in turn shapes the lives of animals in diverse habitats around the globe.
From the frozen poles to the searing deserts, this episode shows how animals have come up with strategies to survive the uneven amounts of sunlight that fall on our planet.
A look at how without volcanoes, there would be no life on Earth. Although destructive, magma from the planet’s molten core builds land, and mineral-rich ash from eruptions fertilises the surface.
