From The True Cost to David Attenborough

Knowledge is power, and in the case of protecting the planet, the more we know about our impact and how we can reverse the effects, the better. As Einstein once said, ‘We cannot solve our problems with the same thinking we used when we created them.’ From uncovering the ‘true cost’ of fashion to unearthing the planet’s best-kept eco practices with Zac Efron, each of these insightful documentaries about sustainability highlights an array of environmental issues – and more importantly, what can be done to reverse humanity’s harmful habits.

The three-part series highlights changemakers who are revolutionising the industry. Green attitudes to fashion, such as the second-hand clothing movement, the rising trend of ‘stitch don’t ditch’, using waste products as materials, circular fashion, and technological means of combatting fast fashion will also feature heavily.

A Netflix original revealing the unsettling reality of commercial fishing and the harm that humans are causing to marine wildlife. From the makers of Cowspiracy, Seaspiracy not only emphasises the devastating environmental affects of the fishing industry, but the disconcerting secrecy and conspiracy surrounding the trade. ‘This film will radically transform the way we think and act on ocean conservation forever,’ says assistant director Ali Tabrizi (who also appears in the film) via Instagram. ‘It is time we focus our ecological and ethical concerns on our seas and its inhabitants. This is a new era for how we treat the most important habitat on earth.’

Joined by friend and health expert Darin Olien, Zac journeys to a number of destinations to learn about wellbeing and environmental efforts across different cultures, from discovering an eco-village in Costa Rica to beekeeping in New York and undergoing a healing vapour bath in Iquitos.
