THE rapid degradation of the environment has long been a major concern for filmmakers, particularly those in the non-fiction genre. Eighteen years back, in 2006, environmentalist and former US Vice President Al Gore featured prominently in Davis Guggenheim’s documentary ‘An Inconvenient Truth’.  This film, widely seen as a milestone in the medium’s engagement with environmental activism, follows Gore as he raises public awareness about the dangers of global warming. It brought climate change to the forefront of the global agenda. The film features a slide show that, by Gore’s own estimate, he has presented over 1,000 times to audiences worldwide.

A year later, ‘The 11th Hour’, directed by Leila Conners Petersen and Nadia Conners, featured Leonardo DiCaprio as co-producer, co-writer, and narrator, driving a campaign to highlight the fragile state of the world’s environment and propose solutions to restore Earth’s ecosystems. With insights from experts, scholars, activists, and leaders, the film explores the complex issue of climate change and calls for immediate action to mitigate its long-term effects. Premiering at the Cannes Film Festival in 2007, ‘The 11th Hour’ garnered worldwide attention.

A decade later, a sequel to ‘An Inconvenient Truth’, titled ‘An Inconvenient Sequel: Truth to Power’, premiered at the 70th Cannes Film Festival. Directed by Bonni Cohen and Jon Shenk, the film documents Al Gore’s ongoing efforts to combat climate change, culminating in the historic signing of the Paris Agreement. It emphasises Gore’s mission to encourage world leaders to invest in renewable energy.

Climate change, deforestation, and extinction are some of the most critical issues of our time, and many leading filmmakers are bringing these topics to life. Over the past decade, numerous impactful documentaries have highlighted the severe consequences of a warming planet. With support from prominent figures in American cinema, the issue of climate change remains in the global spotlight. These documentaries are essential viewing for those concerned about environmental damage and for those who appreciate the power of documentary filmmaking to uncover truths from unexpected places.

Damage mankind has done to the world as well as for those that love the power of documentary films to ferret out the truth from the unlikeliest of places.

Environmental documentaries are, of course, not solely about the dry facts of global warming. Many recent ones have focused on other aspects of nature, industrial practices, and human communities working to protect the environment. 

These films not only reflect the devastating impacts of human activity on the planet but also illuminate the urgent need for change. Through compelling storytelling and vivid imagery, they tell us how mankind is flirting with disaster and why the world must pull back from the brink before it is too late. 

The above three, needless to say, are essential viewing, but along with them here are ten must-watch documentaries that highlight the precarious state of our environment and the steps we need to take to secure a sustainable future.

The final panel of this artwork depicts the catastrophic destruction that humanity faces. ‘Before the Flood’ not only highlights these urgent issues but also provides viewers with actionable solutions, such as reducing meat consumption and voting for leaders committed to environmental sustainability.


New Zealand is the world’s largest dairy exporter, but what was once a source of national pride has become its greatest threat. In the documentary ‘Milked’, Chris Huriwa travels across New Zealand to expose the harsh realities of the country’s multi-billion dollar dairy industry. Through meticulous research, investigation, and interviews with prominent environmental figures such as Jane Goodall and ‘Cowspiracy’ co-director Keegan Kuhn, Huriwa reveals how the industry has exploited animals, consumers, the natural environment, the climate, and the farmers caught in its grip.

‘Milked’ is a powerful and tragic documentary that sheds light on the grim fate of two million unwanted newborn bobby calves, taken from their mothers and sent to slaughter each year. The film also delves into the human and animal toll of diseases like mastitis and mycoplasma bovis, which have necessitated the culling of over 171,000 cows to prevent the spread of infection. The documentary is rich with irony, depicting agribusiness representatives who either deny or are oblivious to the devastating impacts of irrigation on river flows, the use of PKE from Indonesian rainforests, and the brutal treatment of cows and calves. ‘Milked’ also highlights the psychological and financial stress placed on farmers by this industrialised agriculture system, which promises a natural lifestyle but delivers financial pressure and diminishing social acceptance. Farmers find themselves trapped in a system they did not create, feeling alienated and overburdened.

‘Seaspiracy’ is a startling documentary that unveils the environmental toll of fishing and the extent of humanity’s exploitation of the oceans. It advocates for an end to fish consumption and spotlights plant-based seafood alternatives

In New Zealand, 98% of synthetic nitrogen fertiliser is supplied by two companies, Ravensdown and Ballance Agri-nutrients. These companies push fertilisers on farmers but take no responsibility for the resulting climate impacts, river pollution, and health issues.

Beyond the clear environmental and animal welfare concerns, Milked underscores the significant contribution of industrial dairy farming to climate change. Agriculture is New Zealand’s largest climate polluter, with emissions from cows, fueled by massive amounts of synthetic nitrogen fertiliser, and direct emissions from fertiliser application. This industrial dairy system, driven by synthetic nitrogen fertiliser, poses a triple threat to the environment by polluting rivers, contaminating drinking water, and destabilising the climate.


“Seaspiracy” is a startling documentary that unveils the environmental toll of fishing and the extent of humanity’s exploitation of the oceans. The film brings to light the critical state of fish populations, pushed to the brink by commercial fishing practices. It presents powerful scenes from disease-ridden fish farms, shares harrowing accounts of human rights abuses within the industry, and captures the tragic whaling practices in the Faroe Islands. Advocating for an end to fish consumption, “Seaspiracy” also spotlights the rise of plant-based seafood alternatives as sustainable protein sources.

This documentary is a sequel to “Cowspiracy,” offering a deeper look into the lesser-known, yet profound, environmental damage inflicted on our oceans by human actions. Filmmaker Ali Tabrizi, who initially set out to document the beauty of the ocean, instead finds himself confronting the destructive impact of human activities on marine ecosystems. “Seaspiracy” is a compelling call to action, urging viewers to reconsider their impact on the oceans and the planet.


Aaron Gekoski’s debut film, ‘Eyes of the Orangutan,’ is a profound exploration by the renowned environmental photojournalist into the dark world of primate exploitation in the tourism sector. The documentary reveals the heartbreaking reality of orangutans, our sentient relatives, being ripped from their natural habitats and trafficked for entertainment. Produced by Terra Mater Factual Studios, the film poses a poignant question: if we can do this to one of our closest relatives, what hope is there for any other animal?

The film provides a disturbing account of the illegal orangutan trade and the inhumane conditions wildlife animals endure in tourist attractions. The film sheds light on how orangutan-smuggling syndicates work. Despite its unsettling content, ‘Eyes of the Orangutan’ serves as a crucial narrative highlighting wildlife exploitation and tourism, and the discussion whether tourists are just as responsible and complicit in animal abuse as the poachers.


The poaching of elephants for ivory epitomises the unsustainable trade in wildlife commodities, a critical issue explored in ‘The Ivory Game’. Directed by Kief Davidson and Richard Ladkani and produced by Leonardo DiCaprio, the film investigates the global ivory trade, highlighting the conflict between governments and environmental preservationists on one side and poachers and Chinese ivory merchants on the other.

‘The Ivory Game’ focuses on elephant poaching in Africa and its connection to the ivory trade in China and Hong Kong. It emphasises the dire consequences if poaching continues unchecked. Over 16 months, the filmmakers and their crew went undercover to document the slaughter of elephants for their tusks and the smuggling of ivory to China, the world’s biggest market for ivory, where it is cove

The documentary begins in Tanzania with Elisifa Ngowi, the head of intelligence for the Task Force, conducting a nighttime sting operation to arrest Shetani, a notorious poacher responsible for killing 10,000 elephants. In China, Andrea Crosta, head of investigation for Wildleaks, and investigative journalist Hongxiang Huang go undercover to expose the illegal ivory trade. China, the world’s largest market for ivory, complicates the situation by releasing 5 tons of ivory annually to licensed dealers, blurring the lines between legal and illegal ivory.

‘Before the Flood’ presents powerful accounts of rising sea levels, deforestation, and other human-caused environmental damage, and provides viewers with actionable solutions, such as reducing meat consumption and voting for leaders committed to environmental sustainability

This Netflix documentary captures the multi-million-dollar ivory trade in China and Hong Kong, revealing its complexities and the deep-rooted corruption that sustains it. ‘The Ivory Game’ underscores the devastating impact of the ivory trade on the global elephant population, predicting their extinction within the next 15 years if urgent action is not taken. 

The film’s powerful message contributed to significant legislative change, with Hong Kong lawmakers voting in 2018 to ban the ivory trade, a ban that was fully enforced by 2021.

‘The Ivory Game’ serves as a global call to action, warning of the impending extinction of elephants and urging immediate efforts to halt the ivory trade.
