In his stunning documentary A Plastic Ocean, award-winning filmmaker Craig Leeson seeks to highlight the devastating impact plastic waste is having on the ocean, wildlife, and human health, and to offer some solutions to a problem that won't simply go away.

When you throw away plastic, you're unlikely to consider where it actually goes. But in reality, there is no 'away'.

Approximately eight million tons of plastic ends up in the global ocean every year, which has serious ramifications for all life on Earth.

Craig Leeson is an award-winning journalist, filmmaker and founder of the nonprofit Plastic Oceans International.

In 2011 Leeson set out to make a documentary about blue whales in the Indian Ocean, but upon plunging beneath the waterline, found a toxic mix of plastic, oil and waste floating on the surface.

A Plastic Ocean follows Leeson and freediving champion Tanya Streeter on a journey to examine exactly how plastic waste is impacting the planet and its inhabitants, and to discover what solutions are needed.
