On March 22nd, Senator Bernie Sanders and Elon Musk entered a debate over the fate of the world.

It began when Sanders published a very in-character tweet. "We are in a moment in American history where two guys — Elon Musk and Jeff Bezos — own more wealth than the bottom 40% of people in this country," he wrote. "That level of greed and inequality is not only immoral. It is unsustainable."

Elon Musk, the Tesla and SpaceX CEO who briefly surpassed Jeff Bezos in early 2021 to become the wealthiest man in the world, had a ready-made response. In a Tweet, he wrote, "I am accumulating resources to help make life multiplanetary & extend the light of consciousness to the stars."

Sanders's reply remained laser-focused on his lifelong mission to fight income inequality on Earth. He wrote, "Space travel is an exciting idea, but right now we need to focus on Earth and create a progressive tax system so that children don't go hungry, people are not homeless and all Americans have healthcare. The level of inequality in America is obscene and a threat to our democracy."

Musk's starry-eyed statement has since faded into the ether of Twitter, but the context of this debate raises larger questions about futuristic technologies, the present-day interests and needs of humans on Earth, and the ongoing battle between them.

Billionaires dream of flying machines

As the Earth speeds towards irreversible climate disaster, many people's minds have naturally turned towards the stars. The distant, spinning nebulae and gleaming planets above us have long been idealized as potential escape routes for the unhappily earthbound.

But as the climate crisis grows more dire on Earth and space travel ramps up, thanks to ambitious patrons, some (like Elon Musk) have proposed that space may be our best shot at collective survival.

Famously, Musk founded SpaceX because he believed that NASA was not working hard enough to bring humans to Mars, and he feared that humanity is approaching its last chance to escape Earth before our planet becomes an uninhabitable hellscape.

His fellow Bernie Sanders nemesis Jeff Bezos has expressed similarly apocalyptic concerns. Bezos, who founded a rocket and aerospace travel company called Blue Origin in 2000, recently stepped down from his position as CEO of Amazon, claiming he planned on investing more time in his work with Blue Origin and his efforts to fight climate change.

Like Musk, Bezos aims to colonize space by investing ambitiously in new technologies that could help people reach the stars. And also like Musk, he fears for the future of civilization — and sees space as the place where these problems might be solved.

"Hundreds of years into the future, we will move all the polluting industries to space and other planets, where we have infinite resources for all practical purposes and Earth will only be (used for) light industries and residential," Bezos stated in a conversation with Amazon India chief Amit Agarwal in New Delhi.

This plan, which Bezos calls the New Inversion, is a long-term vision that would effectively move all pollution to the cosmos. "I would think, kind of [a] time frame of hundreds of years," Bezos added, reiterating that "we have to preserve this planet and we can do that using the resources of space."

The "space escape" as an escape route for the super-rich

Bezos, Musk, and their future-focused peers may claim that their plans to reach the stars are efforts to ensure a future for humanity, but their own reputations and vast fortunes have raised many questions about who this interplanetary future would actually serve.

At the moment, the future of space travel appears to be reserved for the super-rich — the sort of people who are already least affected by earthly calamities like climate change, despite unleashing the vast majority of the world's carbon emissions. For example, private spaceflight companies such as Axiom reportedly charge up to $55 million to send travelers into specially designed rooms located in the International Space Station.

It is likely that even if space travel begins to evolve in step with Moore's law (the theory that computers' processing power tends to double every two years), whatever world we build in the cosmos will remain reserved for the 1% for quite a long time. In this light, the futures preached by techno-prophets like Bezos and Musk start to look like thin cloaks for a kind of moon-eyed eugenics that would leave billions of people in the literal dust.

"The space barons are shrewdly — one might say cynically — tapping into our respect for astronauts and our idealism about what space represents," Ceridwen Dovey writes in The New Yorker. "They seem to be counting on us to be awestruck by whatever it is they do in space, and to overlook the fact that their motives are not exactly pure, nor are their methods of getting us there egalitarian."

Humans are drawn to mystery and beauty, and space is such a tantalizing frontier that it's difficult to completely write off billionaires' ambitious plans to penetrate it, even though we know their earthly work typically involves hoarding vast amounts of wealth while underpaying and mistreating masses of workers.

The ongoing battle between technological innovation and human-centered reform

Similar contradictions plague a multitude of existing plans to address climate change on Earth, and they are particularly endemic to plans broadcasted by corporate entities who have nothing to gain and everything to lose from substantial climate action.

For example, Jeff Bezos recently pledged $10 billion of his $188 billion net worth to the Bezos Earth Fund, yet his overall approach to climate and philanthropy has continuously come under fire.

First, there's the fact that despite all his talk of concern about climate change, Bezos's company continues to belch out carbon emissions, releasing around 51.17 million metric tons of carbon dioxide in 2019 – up 15% from the previous year despite various green pledges. The company has also been slammed with reports about its poor treatment of workers, and prior to the Capitol riots, Bezos also reportedly donated thousands of dollars to conservative politicians such as progressive disruptor-in-chief Mitch McConnell.

Then there's the fact that Bezos failed to donate more than roughly 0.1% of his net worth prior to his 2020 donations — and the latter comprised less than 8% of his vast net worth, a sum that, along with Musk's wealth, is equivalent to the collective wealth of the United States's poorest 40% of people.

The $10 billion Bezos did donate via the Earth Fund was also met with criticism, particularly from groups invested in climate justice. The vast majority of Bezos's donations went to established environmental organizations like the Environmental Defense Fund and World Wildlife Fund, most of which already possess endowments in the millions. Critics said that many of these contributions will never reach communities already subject to the worst effects of climate-caused floods, wildfires, pollution, and destruction, and many of their ultimate goals involve conserving an existing status quo rather than addressing interconnected crises like racism and economic inequality.

In a statement released in December, a group of community-focused NGOs called the Climate Justice Alliance released a statement in protest of Bezos's donations. It found that "less than a quarter of the first-round grants will go to intermediary funds that support thousands of grassroots communities cultivating solutions on the frontlines of the climate emergency. The inequities couldn't be more striking."

This could also be said of the work of many of the "Big Green" environmental groups, particularly those historically focused on conservation rather than human-focused social change. Conservation movements have historically been bound up with white supremacy, and a look at the bigger picture reveals that white supremacy created and perpetuates the conditions for climate change, itself is an inherently racist crisis.

Other billionaires and corporations' efforts have been subject to similar critiques. For example, Elon Musk recently launched a competition offering $50 million to whomever could invent the best carbon capture techniques. Carbon capture technology has long been an alluring yet elusive potential solution to climate change, and it has also been the recipient of generous funding.

Despite all this investment, no miracle technology with the ability to stop climate change has ever emerged, and waiting for one feels more and more like waiting for a doomsday savior who will never arrive.

False promises further threaten any chance of climate action

An April 2020 study from Lancaster University argues against promises that glorify miraculous technologies, because "overreliance on promises of new technology to solve climate change is enabling delay."

Hinging the solution of climate change on miraculous technological breakthroughs like ice-restoration, nuclear fusion power, massive carbon-eating machines, and extraterrestrial offshoring can "feed systemic 'moral corruption', in which current elites are enabled to pursue self-serving pathways, while passing off risk onto vulnerable people in the future and in the global South," say researchers Duncan McLaren and Nils Markusson, who encourage "cultural, social and political transformation" over placing hopes in instant solutions.

It seems that any genuine "cultural, social and political transformation" will not come directly from billionaires and massive corporations, who naturally often benefit most from current cultural, social, and political structures and hierarchies. Recent corporate efforts to combat climate change have been hollow and hypocritical; and many corporations are being accused of greenwashing as they release statements and pledges that appear to be commitments to fighting climate change but that are really efforts to deflect opposition.

A January 2021 report from the Sierra Club entitled "The Dirty Truth About Utility Climate Pledges" graded utility companies on their plans to cut emissions and transition to clean energy solutions and issued many failing grades to companies that have released "carbon neutral" pledges and similar statements. "

The infuriating truth is that many utilities are not only protecting their coal plants from retirement, but are also actively planning to build out climate destabilizing gas plants," said Mary Anne Hitt, who is the Director of Campaigns at the Sierra Club. "The consequences of allowing utilities to continue to delay the transition to clean energy will be particularly disastrous for low-income communities and communities of color."

Learning from the people and the planet

So where will change come from, if not rockets to stars or carbon pledges or the latest addictive inventions of Silicon Valley coders? Perhaps the answer is not above us but rather below our feet. Perhaps we have everything we need already here on Earth.

"We already have a safe and natural technology for carbon capture and storage (CCS)," writes Francis Seymour in a report for the Center for Global Development. It's called 'tropical forests.'"

We already have everything we need to transition to clean energy, and we already have enough food to feed the world's population. What is needed is a redistribution of wealth and resources — something billionaires, conservative politicians, and oil companies have fought against since climate change was exposed as a dangerous reality in the '80s.

Slowly but surely, the idea of wealth redistribution as an investment in fighting climate change is seeping into reality in the form of modern politics. Joe Biden's infrastructure plan will be paid for, in part, by taxing the super-rich. Still, there's a long way to go.

As things grow more dire, environmentalists increasingly view a cross-racial, cross-class movement as the only feasible solution to climate change. This framework, long supported by environmental justice movements and knitted into intersectional plans like the Green New Deal, sees the solutions to climate change as bound up with ending capitalism, racial injustice, and other interconnected global plagues.

The new vanguard of the climate movement also acknowledges how important Indigenous knowledge of land stewardship and conservation, frontline communities' understanding of environmental racism and the stakes of the climate crisis, and ongoing working class and BIPOC struggles for justice are to any just transition away from a fossil fuel-based economy.

Clearly, billionaires' expensive efforts to colonize space would be low on the priority list of any intersectional response to climate change.

Is there any place for space in the climate fight?

All this being said, it's unlikely that humans will ever totally abandon our desire to explore distant galaxies. Our desire to know the cosmos is as innate as our childhood desires to explore the deep green mysteries of the nearby woods. Fortunately, we don't have to write space exploration out completely in the fight for Earth.

Actually, Jeff Bezos wasn't wrong when he said space could be key to helping us fight climate change. NASA, the UN, and other organizations have consistently reported that some solutions to the climate crisis might be found through space-based technology capable of deepening our understanding of the climate crisis and providing key evidence of its effects.

For example, satellites can detect changing temperature levels, rising sea levels, and other factors that could be vital in the current global effort to halt warming at 1.5°C. On a more theoretical level, thinking about how alien civilizations may have responded to climate change could help us address our own situation.

It seems that for now, space travel's greatest contribution is its ability to help humans look back at Earth — either to measure its changes or to feel awed by what Carl Sagan called our "pale blue dot," as many astronauts have been when they viewed Earth from space and experienced the famous "Overview Effect." (Upon seeing the Earth from space, astronauts report a newfound sense of compassion for and responsibility to the planet and for the interconnected webs of life that live upon it).

Plus, the sheer ambition of the space race provides an excellent blueprint for the kind of effort it will take to actually address the climate crisis. All in all, there is room for space travel within a just transition to an ethical future.

But for now, it seems that the "light of consciousness," as Elon Musk put it, would be best directed towards Earth's living, breathing beings rather than towards a few billionaires and their efforts to further puncture the edges of our already damaged, airless, eternally silent atmosphere.
