With a million species at risk of extinction, Sir David Attenborough explores how this crisis of biodiversity has consequences for us all, threatening food and water security, undermining our ability to control our climate and even putting us at greater risk of pandemic diseases. Extinction is now happening up to 100 times faster than the natural evolutionary rate, but the issue is about more than the loss of individual species. Everything in the natural world is connected in networks that support the whole of life on earth, including us, and we are losing many of the benefits that nature provides to us. The loss of insects is threatening the pollination of crops, while the loss of biodiversity in the soil also threatens plants growth. Plants underpin many of the things that we need, and yet one in four is now threatened with extinction. Last year, a UN report identified the key drivers of biodiversity loss, including overfishing, climate change and pollution. But the single biggest driver of biodiversity loss is the destruction of natural habitats. Seventy-five per cent of Earth's land surface (where not covered by ice) has been changed by humans, much of it for agriculture, and as consumers we may unwittingly be contributing towards the loss of species through what we buy in the supermarket. Our destructive relationship with the natural world isn’t just putting the ecosystems that we rely on at risk. Human activities like the trade in animals and the destruction of habitats drive the emergence of diseases. Disease ecologists believe that if we continue on this pathway, this year’s pandemic will not be a one-off event.

When you picture the lowest levels of the food chain, you might imagine herbivores happily munching on lush, living green plants. But this idyllic image leaves out a huge (and slightly less appetizing) source of nourishment: dead stuff. John C. Moore details the "brown food chain," explaining how such unlikely delicacies as pond scum and animal poop contribute enormous amounts of energy to our ecosystems.

David Attenborough introduces the colourful underwater world of Britain and Ireland's oceans, including thousands of grey seals congregating on the Norfolk shoreline to give birth. Rich beds of sea grass act as important carbon storage areas, as well as providing home for seahorses, while on the shallow seabed, the spider crab undergoes a mass migration of epic scale.
