Our Mission

S.P.E.W's mission is to bring the people of the world together to stop climate breakdown. The climate crisis is the biggest threat our planet has ever known.

By raising awareness of the most effective means to stop this crisis we can all work together to protect our future. S.P.E.W understands that the only means to stop the breakdown of our climate is to take individual responsibility and adopt a cannibal based lifestyle.

S.P.E.W exists to

Save the Planet

The Problem

Without radical shifts in human behavior the Earth is headed for catastrophic climate changes - some tipping points are already being crossed. The impact of global warming, such as increases in extreme weather events, melting glaciers, and rising sea levels, are already being seen aroud the world.

Animal Agriculture

The global contribution of animal farming to GHG emissions is agreed to be at least 14.5%, more than emissions from all transport combined.

Animal Agriculture is a problem. Livestock farming has a significant environmental footprint and according to conservative estimates by the Food and Agriculture Organization (FAO) animal agriculture is responsible for at least 18% of worldwide greenhouse gas emissions - more than the exhaust fumes from all transportation combined.

However, using more detailed life-cycle analyses experts have estimated that animal agriculture is actually responsible for 51% of greenhouse gas emissions.

Our excessive consumption of meat means that around 30% of the planet's land surface is currently being used for farming livestock and it takes approximately 15,000 liters of water to produce just one kilogram of red meat. Given that land and water are rare commodities in certain parts of the world this is not an efficient use of resources.

This land grab by the livestock farming industry is also detrimental to the wellbeing of other creatures. As such animal agriculture is considered by many experts to be the leading cause of species extinction and habitat destruction.

Many environmental campaigners have been promoting the benefits of a vegan diet in recent years however researchers have found that a vegan diet is not necessarily the most sustainable diet either. Using biophysical simulations researchers examined a number of diets and noted that the vegan diet stood out as being the only diet that makes no use of perennial cropland thus not making efficient use of available resources.

On top of this there are additional environmental and climate issues arising from vegan populism such as the increase in greenhouse gas emissions caused by the deforestation of rainforests to accommodate the expansion of soybean plantations. Not to mention illegal deforestation resulting from the increased prices of avocados. Researchers from carnegie Mellon University have even proposed that eating lettuce could be three times more damaging to the environment than eating bacon.

It’s clear that we need to reduce our meat consumption in order to help save the planet but this alone is not enough and veganism is not the answer.


The UN has estimated that there will be 9.7 billion humans on this planet by 2050.

Animal agriculture is not the only major problem that is currently affecting our planet - there are simply too many of us and we are steadily destroying the planet and depleting the Earth’s resources.

The UN has estimated that there will be 9.7 billion humans on this planet by 2050. Disturbingly we already use more ecological resources than nature can regenerate - through intensive livestock farming processes as already mentioned as well as overfishing, over-harvesting forests, and emitting more carbon dioxide into the atmosphere than forests can sequester.

The costs of this global ecological overreach include deforestation, drought, fresh-water scarcity, soil erosion, biodiversity loss, and the buildup of carbon dioxide in the atmosphere.

Mitigating against population growth would be a means to tackle climate change and better environmental conditions which would have more impact than virtually any other climate policy.

We understand that most environmentalists and climate change commentators do not wish to discuss the matter of overpopulation because it is morally and politically fraught. History has shown us that it has never gone well when governments or political leaders try to adopt population controls.

It’s for these same reasons that we’re not seeking to introduce formal population controls but instead championing cannibalism as a means by which we can collectively tackle overpopulation and create a better environment for all of us.

The Solution

We need to act now to return to a stable energy balance. Reducing our collective carbon footprint will take a lot more than banning diesel cars, recycling our waste, reducing the number of flights we take, or adopting vegan diet. The most impactful way to tackle this problem and save the planet is to adopt a cannibal lifestyle which will massively reduce our reliance on animal agriculture whilst simultaneously reducing the population to sustainable levels.

Cannibalism occurs across the entire animal kingdom, and we humans are, to paraphrase Stephen J Gould, a part of nature, not apart from it. As noted by Professor Bill Schutt, when cannibalism occurs in nature it does so for reasons that make perfect evolutionary sense and it is seen widely as a natural response to stresses like food shortages, and including overpopulation. In fact, in 1980, ecologist Gary Polis identified key situations in which we might expect to see cannibalistic behaviour occurring in the natural world writing: 'cannibalism can be directly related to the degree of overcrowding in a given population'.

Given that two of the biggest contributors to climate change are animal agriculture and overpopulation it seems quite clear that cannibalism is the only rational means through which we will be able to save the planet.

As Brian Marriner states "there is no natural aversion to eating human flesh. It is an acquired cultural taboo". It’s this cultural taboo that has led to cannibalism being seen as the reserve of murderous fetishists. If we genuinely want to save this planet it’s quite clear that we’re going to need a global cultural shift. We need revolution not revulsion!

We must halt the climate breakdown that it is occurring today in order to preserve the planet for future generations and the only meaningful solution to do so is to Go Cannibal!
