Renowned natural historian and british broadcaster Sir David Attenborough has a new documentary in the pipeline, this time to urge people to ditch meat in preservation of the planet.
David Attenborough: A Life On Our Planet recounts the 94-year-old’s extraordinary encounters with the natural world, exploring some of his defining experiences as a naturalist, and also the devastating changes he has seen unfold over six decades in the field.
“The way we humans live on Earth is sending it into a decline,” says Attenborough in the official trailer for the film set to release in cinemas on the 28th of September. “The planet is headed for disaster. We need to learn how to work with nature, rather than against it.”
A Life On Our Planet unpacks the deterioration of Earth’s environment, focusing on the loss of biodiversity as a result of industrialised agriculture. Sir David Attenborough’s message urges people to reduce the amount of meat that they consume, just as he has in recent years, because “the planet can’t support billions of meat eaters.”
By taking on a lower-impact plant-based diet, human beings could increase the yield of the land, reducing the need to clear forests to create the space needed to meet current agricultural demands.
Despite the pressure placed on the planet by modern farming practises, Attenborough explains that it’s not too late to stop the deterioration of Earth’s ecosystem. “We must restore biodiversity. We must rewild the world – and rewilding the world is easier than you think. A century from now, our planet could be a wild place again.”
The documentary will be available on Netflix before the year’s end, hopefully resulting in a shift in the way we consume and encouraging sustainable behaviour across the globe.

The production, consumption and wastage of food are influential elements of health for both people and the planet. With a predicted population increase of 2-4 billion people by the year 2050, and an already suffering environment, food will continue to be a major issue in the 21st century unless we change now.
In the recently released EAT-Lancet Commission report, it was stated that “food is the single strongest lever to optimize human health and environmental sustainability on Earth”. It’s no secret that global food production is one of the biggest threats to climate sustainability, and this begs the question: what constitutes a sustainable diet? The answer is green and simple. “A diet rich in plant-based foods and with fewer animal source foods confers both improved health and environmental benefits.” says Walter Willett, MD, professor at Harvard T.H. Chan, school of public health.
While some people may believe that ditching meat, dairy and other animal by-products is too extreme a sacrifice, others believe that the personal and environmental benefits make the choice a no-brainer. The potential health benefits alone are quite convincing. When it’s done right, a vegan diet can lower cholesterol enough to significantly reduce your risk of heart disease. Veganism can also lower the likelihood of developing type 2 diabetes and certain types of cancer, such as colon and prostate cancer. Additionally, cutting out animal products is also known to help people to lose excess weight, and with an approximate 13% of the world’s adult population classified as obese in 2016, this may well be enough of a reason to make the change.
The consumption of meat and other animal products contributes to widespread pollution, global warming, land degradation, deforestation, water scarcity, global hunger and species extinction. In fact, according to this source, the diet of a meat eater creates seven times the greenhouse gasses as the diet of a vegan. If every American dropped a single serving of chicken from their diet per week, it would save the same amount of CO2 emissions as taking 500 000 cars off the road. You’d save more water by not eating one pound of meat than you would by not taking a shower for six months. Raising animals for food uses 30% of the Earth’s total land mass, occupying more space than the entire surface of the moon.
The numbers are clear: meat-heavy diets are a waste of resources, and switching to a plant-based or vegan diet is one of the most effective ways to reduce your ecological footprint. While a vegan diet is widely believed to be beneficial for the planet, not all plant-based products are green and sustainable. Products like Oreos and Kelloggs cereals, while tasty and vegan, are doing vast damage to the environment because they include an ingredient called palm oil. Palm oil plantations accelerate the global temperature rise, release massive amounts of CO2 and directly threaten 193 of the world’s critically endangered species, including the Bornean Orangutan (source: International Union for Conservation of Nature). It goes without saying that vegan products which include palm oil are not green, but rather mean.
There is a dire need for change in the global food system and we, as consumers, have the ability and responsibility to vote with our money. Our demand (or lack thereof) affects the supply of either sustainable or unsustainable foods. Above all, the most environmentally friendly diet you can follow is one that includes locally sourced, plant-based foods. Opting for whole foods that don’t involve processing and packaging is the best way to reduce your environmental impact while properly nourishing your body.
The switch to veganism doesn’t have to mean ‘all or nothing’: meat can be phased out progressively, one meal at a time, and with the hoard of recipes and resources accessible online, there’s hardly an excuse not to give it a try. Changing to a vegan diet does mean eliminating certain foods, but it also provides an opportunity to improve your physical health, that of the planet, and to explore many new and exciting flavour combinations that are clean, green and simple.
