Young filmmaker Julia Barnes embarks on a journey around the world to investigate the causes and solutions to some of the most pressing threats facing the oceans, such as the decimation of the world’s fish populations and ocean acidification. Through interviews with scientists, researchers, and activists, the film reveals the interconnections of all life on earth, positing that the current mass extinction in the oceans will have devastating impacts on terrestrial life too, including humans. Sea of Life becomes a call to action, with the view that once more people know what’s happening in the ocean, they’ll want to fight for its protection. Barnes then documents some of the largest environmental rallies, including the People’s Climate March in New York and protests at COP21 in Paris, but concludes that these actions will not be enough to save our future. Sea of Life calls for a revolution in the way we approach activism.

Half of all marine life has been lost in the last 40 years. By 2050 there will be more plastic in the sea than fish. The way the ocean is different to how we thought 100 years ago. We can no longer think of it as a place of resources, a dumping ground, immune to change or decline. Blue takes us on a journey into the ocean realm, witnessing the critical moment of our time when the marine world is on the precipice. Passionate advocates for ocean preservation take us into their world where the story of the changing ocean unfolds. We meet those who are defending habitats, campaigning against exploitative commercial fishing, combating marine pollution, and fighting for the protection of keystone species. Blue comes at a time where decisions made today will pave the legacy for what we leave behind for generations to come.

The microbeads of plastic contained in cosmetics, shower gels, soaps, toothpastes, and many other products, of course directly end up in rivers and oceans, fish and birds, as well as other creatures of the sea and indeed land. But if that isn’t problematic enough, these tiny plastics are only part of the bigger problem of plastic prolifically choking the ocean to death. For all plastics, big or small, break down and fail into smaller plastic particles, having cumulative biological and toxicological effects. This short television report takes a quick look into how marine life is effected by all this, and why we should do something about it before it’s too late.

Leviathan is an immerse film documenting the toll that commercial fishing continues to take on the life of the ocean. The message is explicit in the imagery of the film, which largely avoids exposition and context; goes on without narration, unfolding largely in the dark of night. Attesting to the power of estrangement and visceral imagery, Heavy-metal music coincides with heavy machinery, grinding gears and chains, to also similarly portray the repetitive hard-work of trawling life, against the collapse of ocean-life.

Decades of over-fishing by the global tuna industry have now pushed the final frontiers to the waters of Papua New Guinea. In the 1950s, commercial fishing was extracting 400,000 tons of tuna from the ocean. This number is now close to 4 million tons. And it comes at a high cost: a human one, now affecting the last places on Earth to receive the full impact of globalisation. Set in “the land of the unexpected,” in the north-eastern part of Papua New Guinea, Canning Paradise follows the struggle of Indigenous tribes to protect their way of life, guarded by traditions dating back since the beginning of time. While many have lost hope, others are fighting for survival from the corrupt government and the omnicidal dominant culture.

Plasticized follows an ocean journey with the 5 Gyres Institute, a non-profit organisation that focuses on reducing plastics pollution through research. The expedition was the first scientific journey looking at plastic waste across the South Atlantic Ocean. The film takes a look at one of the institute’s global missions: studying the effects, reality and scale of plastic pollution around the world. The boat skims the surface of the ocean by trawling, in order to examine the toxic effects of plastic pieces to tissues of marine life. Many tiny bits of plastic are found contaminating the waters, and they’re sometimes not seen because the rough waters push them down. Every few kilometres, one teaspoon of plastic is collected. This may not seem like much, but this amount adds up substantially, considering that the ocean is vast and covers two-thirds of the planet.

On April 22, 2010 the Deepwater Horizon offshore drilling rig, run by oil giant BP, sunk into the Gulf of Mexico—creating the world’s biggest and most catastrophic environmental crime in history. After over 750 million litres of crude oil and millions of litres of the chemical dispersant Corexit dumped into the sea, the disaster was deemed over and all damage repaired. This is bullshit however. Film-makers Josh and Rebecca Tickell travel to the Gulf of Mexico to document first-hand the extent of environmental and community damage, continuing many years after the explosion. Beginning by tracing BP’s origins and fingerprints across decades of US manipulation in Iran, The Big Fix assembles an indictment of this monumental disaster by unpacking the workings of the complex oligarchies that put pursuit of profit over all other ends…

Canada’s tar sands are the largest industrial project ever undertaken—spanning the size of England. Extracting the oil and bitumen from underneath unspoiled wilderness requires a massive industrialised effort with far-reaching impacts on the land, air, water, and climate. It’s an extraordinary industrial spectacle, the true scope of which can only be understood from an aerial view. Shot primarily from a helicopter, Petropolis: Aerial Perspectives on the Alberta Tar Sands offers an unparalleled view of the world’s largest ever industrial project…

Poisoned Waters investigates some of the root causes of what we see worldwide with ecological collapse, dead-zones and pollution effecting oceans, rivers and watersheds. With a focus on major waterways in the United States such as the Chesapeake Bay and Puget Sound, the film follows the culmination of decades of evidence that today’s systemic and growing environmental collapse comes not only from the toxic activities of industry, agriculture and massive suburban development; but also from the permeated satiety of chemicals in prolific consumer products such as face-creams, deodorants, prescription medicines and household cleaners. This is a startling reminder of the compounding threat facing our world and the need to act imperatively.

The Cove analyses and questions Japan’s dolphin hunting culture, being a call to action to halt mass dolphin kills, to change commercial fishing practices and to inform and educate the public about the risks and ever increasing hazard of mercury poisoning from dolphin meat. Told from ocean conservationist Richard O’Barry’s point of view, The Cove documents a group of Taiji fishermen who engage in mass dolphin kills, which in large part, are motivated by the tremendous revenue generated for the town by selling some of the captured dolphins to aquariums and marine parks. The dolphins that are not sold into captivity are then slaughtered in the cove and the meat is sold in supermarkets…

Following on from the series Planet Earth which looked at various forms of life across the globe, Planet Earth — The Future highlights the issues of conservation and the future of the environments and species featured in the Planet Earth series. Using interviews with the film-makers and eminent figures from the fields of science, conservation, politics, and theology, the series poses questions around the effectiveness of the environmental movement, and the future of the planet. A lot needs to change in order to ward off catastrophe…

Deep Trouble covers the concerns of commercial fishing from a global perspective. Many species of fish that are eaten every day all around the world are now seriously threatened or are critically endangered. The Southern Bluefin Tuna for one. Mainstream awareness of where market fish come from let alone how endangered they might be is minimal. As fish stocks dry up, supermarkets are now offering new and strange species from the deep sea. Bizarre-looking creatures are being dragged up in vast fishing nets from depths of 1,000 metres or more, and the methods used to catch them are horrifying. How sustainable is this?
