Will explore the strategy, deception and feats of engineering plants use to thrive in the changing weather of different seasons. In the face of conditions ranging from ice and snow to raging fires, survival is often a question of perfect timing - particularly when contending with intense competition and surprising predators.
In this episode, David Attenborough travels to Finland to show one of the most extreme examples of seasonal plant life in the Arctic Circle. He also travels to California to see how climate change is affecting giant sequoias. These ancient trees like all other seasonal plants depend on the predictability of the seasons and our current changing climate threatens their survival.

Filmmaker Ali Tabrizi initially set out to celebrate his beloved ocean, but instead found himself examining the harm that humans inflict upon the vulnerable seas. From plastics and fishing gear polluting the waters, to the irreparable damage of bottom trawling and by-catch, to illegal fishing and devastating hunting practices, humanity is wreaking havoc on marine life and, by extension, the entire planet. What Tabrizi ultimately uncovered not only challenges notions of sustainable fishing but will shock anyone who cares about the wonders of ocean life, as well as the future of the planet and our place on it.
From the co-creator who brought you the groundbreaking documentary Cowspiracy comes Seaspiracy, a follow up that illuminates alarming -- and not widely known -- truths about the widespread environmental destruction to our oceans caused by human behavior.

The most spectacular moments from the Seven Worlds, One Planet series that highlights the incredible rich and wonderful diversity of life found on our planet's seven unique continents. Millions of years ago incredible forces ripped apart the Earth's crust creating our seven continents - each with its own distinct climate, its own distinct terrain and its own unique animal life. Narrated by David Attenborough.

A humpback whale mother and calf embark on an epic journey from tropical coral paradises to storm ravaged polar seas. Newly discovered coral reefs in Indonesia reveal head-butting pygmy seahorses, flashing 'electric' clams and bands of sea kraits, 30-strong, which hunt in packs. Elsewhere plagues of sea urchins fell forests of giant kelp. Huge bull fur seals attack king penguins, who despite their weight disadvantage, put up a spirited defence.

Brian explores the physics of the size of life through some close encounters with Australia's wildlife. From swimming with great white sharks to tracking red kangaroos, he discovers that the size you are profoundly affects the life you lead and, ultimately, how long you have to enjoy it.

Bladderwort utricularia is a pond-dweller that is among the fastest known, its traps snapping shut in less than a millisecond. As the seasons change, David demonstrates how plants operate on a different time scale to us; how they modify their lives according to the time of year. We discover insects’ hidden links with plants, both as pests and pollinators. UV-sensitive 3D cameras reveal the invisible alter-ego of plants and their flowers’ mesmerizing patterns; a parallel-dimension of strange colours and stunning patterns through which plants communicate with them. With the aid of visual effects, David steps among the swirling vortices of plant scent; communication signals with which plants are inextricably plugged in to the natural world. And using a tuning fork, he demonstrates how plants and insects can even communicate with music. As autumn envelopes the Gardens, fungi reveal themselves not as the enemies of plants but their vital allies. In Kew’s atmospheric Fungarium, David discovers a specimen that has the power of mind control and another that lives underground where it has grown to be so big it can be counted as the largest single organism on the planet. It is 6 times bigger than Kew Gardens itself.
