BBC - Human Planet S01E01 Oceans: Into the Blue (2011)

Human Planet is an eight-part landmark BBC natural history series. Filmed in high definition, Human Planet will be an epic record of man's survival in the most extreme environments. Each episode focuses on one environment and how the peoples and tribes who live there adapt to their surroundings: oceans, deserts, arctic, jungles, mountains, grasslands, rivers and cities.

As an air-breathing animal, the human is not built to survive in water. But people have found ways to live an almost aquatic life so they can exploit the sea's riches. From a 'shark-whisperer' in the Pacific to Brazilian fishermen collaborating with dolphins to catch mullet, this journey into the blue reveals astonishing tales of ingenuity and bravery. Daredevil Galician barnacle-collectors defy death on the rocks for a catch worth 200 pounds per kilo. In Indonesia an epic whale-hunt, using traditional hand-made boats and harpoons, brings in a sperm whale. The Bajau 'sea gypsies' of the Sulu Sea spend so much time on water they get 'land sick' when they set foot on the land! We dive 40 metres down to the dangerous world of the Pa-aling fishermen, where dozens of young men, breathing air through a tangled web of pipes attached to a diesel engine, capture thousands of fish in a vast net. We see how surfing has its origins in the ancient beliefs of the ocean-loving Polynesians, and we join a Borneo free-diving spear-fisherman on a breath-taking journey 20 metres down in search of supper.

Oceans episode facts:
• Oceans and seas account for over 70% of the world’s surface area.
• The oceans contain around 97% of all the water on Earth.
• The oceans support the life of nearly 50% of all species on Earth.
• Over one-third of the total human population, nearly 2.4 billion people, lives within 100 km (60 miles) of an oceanic coast.
• One billion people rely on fish as an important source of protein. As many as 90% of all the ocean's large fish may have been fished out.
• The oceans absorb 50% of the carbon dioxide humans release into the atmosphere by burning fossil fuels for energy, as levels increase this leads to an increasing acidification of the oceans.
