Скачать или смотреть The Impossible Biology of the Giant Sequoia | How the World’s Largest Trees Survive

In just 3 minutes, discover the Impossible Biology of the Giant Sequoia. How do they pump water 300 feet against gravity? And why do they need fire to stay alive?

The Sequoiadendron giganteum defies the laws of physics. Standing nearly 300 feet tall in Yosemite's Mariposa Grove, these biological titans face engineering problems that should kill them: immense gravity, crushing weight, and forest fires.
This mini-documentary breaks down the science of how the world's largest trees survive. We look at their unique Hydraulic Engineering (drinking from the air) and their surprising dependence on fire (Serotiny) to reproduce.
Scientific concepts covered:
-Fog Harvesting: Beating gravity by drinking from the sky.
-Serotiny: The biological need for forest fires.
Shallow Roots: How they support 2 million pounds of weight.
