“Do everything you can possibly do, and then a lot more” – Kevin Anderson.

Dear Climate Healers,

On this World Environment Day, I wanted to reach out to you with an important update on our responsibilities at Climate Healers.

It has been nearly two years since we won the debate at the Oxford Union. The video of my speech at the debate has been receiving some fresh attention of late, thanks to its endorsement and revival on the Plant Based News channel.

One good thing about Artificial Intelligence is that it has verified the soundness of our calculations in the Climate Healers animal agriculture position paper and this has renewed public interest in the Climate Healers message.

We have all heard the time-worn cliche, “There is NO Planet B.”

Our message is the opposite. We believe that we are now living in an extraordinary time at the tipping point between two distinct worlds.

Planet A is the world we were all educated into — a system built on extraction, domination, deception and denial. It’s a world where 90% of American adults have been miseducated into believing that protein is ONLY found in animal foods. It is a world where forests are clear-cut for animal agriculture, oceans are emptied for profit, and mothers are separated from their babies in the name of food to satisfy nutritional needs that do not exist. It’s a world overheating, unraveling and collapsing under the weight of its own violence.

Our message is that you don’t have to stay in that dystopian world of Planet A.

What is Planet B?

Planet B is the world of Planet A turned upside down.

All around us, people are restoring Planet B – a just, regenerative and life-affirming world, the world of truth and innocence we were all born into. Planet B is rooted in compassion, community, and ecological healing. It’s a world where animals are free, cages are empty, food is grown in harmony with the Earth, and no one is left behind.

It is a world where commerce is compassionate and conducted as a service to all life, not as a self-enrichment venture.

Returning from Planet A back to Planet B is the most important journey of our time. It’s not just about policy or technology — it’s about values, imagination, and courage.

It’s not to reform the obsolete systems of Planet A.

It is to hospice what must end, and midwife what must be reborn.

It is building bridges — helping farmers, workers, and communities move from harm to healing.

It is creating a new story — the story of the thermostat species that reconnects us with all life and guides us home to fulfill our responsibilities on a thriving planet.

This isn’t a dream. It is already happening.

The question before us on this World Environment day is: what role will you play in the rebirth of Planet B?

Not in some distant galaxy. Not buried beneath layers of science fiction.

You don’t have to board a spacecraft. No space suits. No oxygen tanks. No trillion dollar budgets. We already have everything we need to rebirth Planet B.

Because we won’t find Planet B out there with a telescope, but inward with a microscope – examining our values, our choices, our way of life. Right here on Earth.

Planet B isn’t light years away – it’s lighting up a new way of living.

It’s a shift in consciousness, a transformation in culture, a return to harmony.

On Planet B, you don’t work to survive. You live to thrive.

Nutritious food is abundant and available to everyone.

The air is clean. The land, unspoiled.

There’s no competition, no propaganda, no fear.

Everyone is welcome.

On Planet B, you don’t lack money. You don’t need fame. You simply belong.

The only “rent” you pay on Planet B?

To protect its pristine beauty.

To keep it clean and alive for the children of the future.

That’s it.

And if you’re concerned it’s too good to be true… Don’t be. You’re not dreaming. You’re finally just waking up to the world you were born into.

This isn’t a fantasy.

This is a choice.

Planet B is real. It’s a lot closer than you think. And it’s waiting for you.

In my new book, “There IS a Planet B,” I presented a roadmap.

And it starts with a simple, yet powerful first step.

A Powerful First Step

It is to go Vegan – as if our lives depend upon it. Because they do…

Going Vegan is the single most important step that we can take to restore the life support systems on Earth and transform Planet A into Planet B. We debated this exact proposition at the famous Oxford Union, one of the most prestigious debating societies in the world, and we won the debate handily.

What emerged was The Oxford Consensus that the world would go Vegan as soon as possible.

Going Vegan means adopting a “philosophy and way of living that seeks to exclude, as far as is possible and practicable, all forms of exploitation of animals for food, clothing or any other purpose.”

This is a journey, not a destination. We have consistently recommended this journey on spiritual, health, ethical and environmental grounds.

But let me now reiterate the environmental reasons to go Vegan.

Fixing Life Support Systems on Earth

It is undeniable that the obsolete systems on Planet A have adversely impacted life-support systems on Earth. Scientists at the Stockholm Resilience Center have identified nine planetary boundaries that we must stay within for the sustainability of life on earth. At the moment, we have transgressed six of them and any one of these transgressions could end life as we know it.

The good news is that when we go Vegan, we help resolve all six of them. That’s the collective power we have as individuals to reverse our existential crisis.

We now know that animal agriculture is the leading cause of ecological destruction because it uses 37% of the ice-free land area of the planet just to graze animals, while bottom trawling an area of the ocean floor the size of South America every year for industrial fishing.

Animal agriculture is the only major activity in which we destroy forests and replace them, not with other trees for timber or paper, but with grass, which drastically reduces the carbon storage as well as the diversity of life that the land can support.

Animal agriculture is the primary reason why humans have reduced the number of trees on the planet by half, from 6 trillion down to 3 trillion, over the past 10,000 years7. Restoring those 3 trillion trees and rejuvenating the soil that they live on can draw down enough carbon to potentially reverse climate change.

Animal agriculture is grossly inefficient because animals must eat 39 pounds of plants to produce one pound of so-called human food, on average, a burden which is already beyond what the Earth can support.

By going Vegan, we can give nearly 40% of the ice-free land area of the planet, as well as the entire ocean, back to nature.

When we restore the native ecosystems on that land, we can grow most of the 3 trillion trees that we cut down over the past 10,000 years. This helps resolve all six planetary-boundary transgressions.

The least violated transgression is fresh-water change. Rewilding the land that is currently used for grazing animals will restore the fresh-water cycles of the planet.

The next is land-system change. Going vegan will allow us to return nearly 40% of the ice-free land area of the planet back to nature, resolving this planetary-boundary transgression.

The next worst transgression is climate change, which can be resolved when the excess carbon in the atmosphere is absorbed in the trees and soil that we can restore to the ecosystems of the planet.

The next is chemical pollution, which would be safely stored away in regenerating forests when we go Vegan. Eating animal foods currently delivers concentrated doses of this chemical pollution into our bodies through bioaccumulation. Therefore, going Vegan addresses chemical pollution for both the Earth and ourselves.

The next worst transgression is nitrogen and phosphorus loading, mainly through our overuse of synthetic fertilizers for crops. Since over half the crop outputs are fed to farmed animals, going Vegan will resolve this transgression as well.

All of these transgressions impact wildlife, and biodiversity loss is the worst of the six planetary-boundary transgressions.

By restoring habitats for wild animals and allowing them to live freely in the ocean, we will resolve this transgression as well. If instead, we let wild animals die, we die.

“House on Fire” Urgency

Finally, there are two explanations for perhaps the gravest threat ever posed to civilization – and to all life on earth: – the “house-on-fire” urgency of runaway climate change.

This keeps me up at night because, as a systems engineer, I have spent my entire career examining nonlinear feedback loops and learning how to model them. I have watched circuits melt in the lab because some feedback loop was not modeled correctly.

Do you know when even the most skilled scientists realize that they have triggered an irreversible tipping point in a complex nonlinear feedback system?

When it is too late.

One explanation for the cause of climate change–the one we hear about all the time from our leading climate spokespeople–is the burning of fossil fuels.

It is certainly true that the burning of fossil fuels contributes greenhouse gasses to the atmosphere, thereby warming the planet.

But that’s only half the story.

The other explanation – what we call the Cow in the Room—is rarely addressed: the human folly of exploiting animals that is animal agriculture.

When these two sources of global warming are compared in the media, fossil-fuel burning is always emphasized, and is almost always assigned the greater responsibility for warming the planet.

But the opposite is true. You see, the other half of the story is that the burning of fossil fuels also contributes aerosols to the atmosphere, which cool the Earth. This is known as the Faustian bargain of fossil fuels and it has been documented in scientific papers and UN reports for decades.

The cooling aerosols are short-lived which means that if we rapidly phase down fossil fuel use without urgently going Vegan, we will increase the human-caused warming of our planet by anywhere from 50 percent to 90 percent within a few weeks. That is the last thing we should be doing if we are trying to prevent runaway climate change.

On the other hand, when you factor in the potential carbon absorption of the forest land cleared for animal agriculture, you find, with any honest accounting –as we published in our position paper –that animal agriculture is responsible for at least 87% of greenhouse gasses on an annual basis11.

That calculation did not include the respiration of farmed animals. It did not include the bottom trawling of the oceans by industrial fishing. It did not include the carbon released by pasture-maintenance fires set annually on grazing lands around the world. It did not include the loss of phytoplankton populations and sea forests due to industrial fishing.

These factors were not included mainly because they haven’t been reliably assessed due to a futile attempt by the climate orthodoxy on Planet A to hide the Cow in the Room. But it is clear that if we could estimate these factors and include them in the calculation, we would find that animal agriculture is responsible for – wait for it – well over 100% of greenhouse gas emissions into the atmosphere.

Now that sounds unbelievable. How could it possibly be responsible for more than 100%? Because the evidence points to the possibility that the earth will not only stop warming, but will actually start cooling in a Vegan world even if we continue to conduct all our other activities as we do today.

As an aside, the earth will only cool, assuming that we haven’t already gone beyond the point of no return on some climate feedback loops. In the latter case, we won’t find out until we all go Vegan and verify whether the feedback loops respond in the right direction.

The cessation of animal agriculture can result in healthy oceans, healthy forests and healthy soils, and if we want to reverse climate change, then we must adopt a strategy that can draw down greenhouse gasses from the atmosphere. Healthy oceans and sea forests can do that. Healthy soils and trees can do that.

Solar panels and electric cars cannot.

Now, we are not supporters of the fossil-fuel industry–far from it. Our Climate Bathtub model has shown that we must wean ourselves off fossil fuels gradually, after the world urgently goes Vegan. But we burn fossil fuels to heat and cool our homes, to transport ourselves, to manufacture goods, to ship goods. These are all social goods.

What social good comes from animal agriculture? Nothing. Only obesity, heart disease, diabetes, cancer, biodiversity destruction, soil depletion, fouling of our water sources, antibiotic resistance, dangerous and dehumanizing work, animal cruelty, climate catastrophe, world hunger and let’s not forget pandemics. Indeed, there is nothing that will not improve when we end the cruelty and folly of exploiting animals.

These are just the scientific reasons to Go Vegan, but lasting change comes not from the head, but from the heart. In that regard, we have all made pinky promises to the children in our lives that the world will go largely Vegan by 2026, which is the year humans will have killed almost all the wild animals on Earth if we don’t change course.

That is simply unthinkable and as Climate Healers, we cannot and will not let it happen.

When our house is on fire, do we not do everything in our power to save our fellow residents?

Of course, we do. We don’t pass by our sleeping brothers and sisters thinking that they are better off finding out for themselves once their own hair or clothes catch fire.

We have a duty to expose the Faustian bargain of fossil fuels as well as the Cow in the Room that are being hidden by the climate spokespeople on Planet A.

As Climate Healers, we have always shown the courage to face facts and do what is necessary, not just what is politically possible.

In essence, we now have the grand opportunity to abandon Planet A and embrace Planet B as the true caretakers of Earth. Go Vegan. End animal agriculture and save the world.

Yes, that might seem like an impossibly hard task to accomplish by the end of 2026, but is it really?

Thank you for all that you do, from the bottom of my heart!

With much love,
