In How Trees Prepare for the Toughest Seasons, narrator Sir David Attenborough explains how trees survive harsh winter environments. In northern forests, trees prepare for the cold by pulling water into their trunks and creating a sugary antifreeze. But while most trees lose their leaves, pine trees can survive temperatures as low as -40°F and keep their needles all winter. One special type of pine, the bristlecone, can live for up to 5,000 years, with its cones growing for only six weeks each year. This video is excerpted from BBC's Life, a show that explores the remarkable strategies animals and plants use to ensure their survival.
In Polar Seasons and Life at the Extremes, narrator Sir David Attenborough describes life in the coldest, most extreme places on the planet. Learn how the seasons at the Poles have a rhythm of their own that only the toughest species can endure. This video is excerpted from BBC’s Frozen Planet, a series that shows a fragile world of beauty and hostility, where nature finds a way to survive and thrive in frigid conditions.
In The Epic Battle Between Salmon and Bears, narrator Andrew Scott describes how, as autumn arrives in southern Alaska, the landscape transforms along with the weather! Chilly temperatures and storms bring heavy rain, flooding the rivers just in time for one of nature’s greatest events. Millions of Pacific salmon make their epic journey upstream, leaping over waterfalls while hungry grizzly bears wait for their biggest feast of the year. The bears battle for the best spots, catching up to 30 salmon a day to pack on weight for the winter ahead — but for the salmon, it’s a life-or-death challenge to make it home. This video is excerpted from BBC’s Earth’s Great Seasons, which reveals how seasonal changes shape the planet and its wildlife.
