Immense shoals of fish throng our shallow seas. Small fish, in turn, sustain bigger ones. The rich coastal seas are the fishing grounds of our planet and can provide an abundance of food for wildlife and humanity. The seas fringing land make up less than a tenth of the world's oceans but 90 percent of marine creatures live in coastal waters, from fearsome sharks to lowly urchins. Protecting these habitats is a battle humanity must win.

The Southern Ocean, which circles the globe without being blocked by land, is home to the Antarctic Circumpolar Current (ACC), the longest of the world's ocean currents. Also known as the "channel", it connects the Indian, Atlantic and Pacific Ocean basins and exerts a powerful influence over the Earth's climate. The ACC carries 150 times more water around Antarctica than the flow of all the world's rivers combined.

The Sea of Cortez, also known as the Gulf of California, is a unique corner of the Pacific Ocean. This remarkable young sea is thought to be around five million years old and home to nearly 900 species of fish and the widest variety of whales and dolphins found anywhere on Earth. Some of the greatest changes threatening the world's oceans today can be seen in this stretch of water.

In 1971, after being rejected by Hollywood, Bruce Lee returned to his parents' homeland, Hong Kong. Over the next two years, he'd complete four iconic films that would define his legacy, a legacy cut short when he died, stunningly, in the summer of 1973. He was 32 years old. Directed by Bao Nguyen, 'Be Water' is a gripping, fascinating, intimate look at not just those final, defining years of Lee's life, but the complex, often difficult, and seismic journey that led to Lee's ultimate emergence as a singular icon in the histories of film, martial arts, and even the connection between the eastern and western worlds.
The film chronicles Lee's earliest days, as the son of a Chinese opera star born while his father was on tour in San Francisco, and then raised in Hong Kong over what became an at times troubled childhood. Sent to live in America at the age of 18, he began teaching Kung Fu in Seattle, and established a following that included his future wife, Linda. His ambition ever rising, Lee eventually made his way to Los Angeles, where he strove to break into American film and television. There, despite some success as a fight choreographer and actor, it was clear Hollywood wasn't ready for an Asian leading man - and so he returned to Hong Kong to make the films that would in fact make him a legend, his international star skyrocketing just as his life was cut short.
'Be Water' is told by the family, friends, and collaborators who knew Bruce Lee best, with an extraordinary trove of archive film providing an evocative, immersive visual tapestry that captures Lee's charisma, his passion, his philosophy, and the eternal beauty and wonder of his art.

We routinely talk about healthy food and clean water, but how often do we spare a thought for what enters our lungs? The World Health Organization calls air pollution the silent killer. Air pollution is proven to shorten our lifetimes and it hits the vulnerable - children, the sick and the elderly - hardest of all.
Prince William, Sir David Attenborough and astronaut Naoko Yamazaki hear the personal stories of people who are directly affected by air pollution and show us incredible solutions.

Take another walk on the wild side with our favourite pets. Extraordinary photography reveals their hidden senses and secret communication skills. Dogs take a car trip through Paris, using their legendary sense of smell to show us a very different city. A hamster uses his remarkable senses to stage a great escape and then deploys more navigational talents to find his way home. Cats become intoxicated on the scent of a plant and suffer the consequences. A budgie shows his hidden charms to his mate as, under UV light, his crown and cheeks positively glow. Goldfish reveal secret senses that can detect the slightest water movement. A guinea pig gives birth and the newborns receive surprising care from their father. In South America, where guinea pigs have lived with people for 7,000 years, they express the true meaning of their entertaining calls. When we groom a horse we speak their language, but horses use ears to communicate in ways that we are rarely aware of. In Japan cats show their secret messages and in Peru dogs reveal the hidden signs that allow them to communicate across a city. Packed with extraordinary facts and wild behaviour - you'll never look at your pet in the same way again
