There is no doubt about it: people are changing the Earth’s climate. The evidence for what scientists call “anthropogenic climate change” is overwhelming, notwithstanding the obfuscation efforts of the climate change denial industry kept on life-support with infusions of corporate money.
But to say that our emissions of greenhouse gases are causing climate change is not to say that every extra person automatically multiplies the problem. Nor does it imply that population control is the ultimate solution – a view espoused by some on the Malthusian fringe of the environmental movement.
The Washington-based NGO Population Action International claims that human population trends are “a major driving force of emissions growth.” Flashing the simple but misleading equation “More people = more emissions” on its website, the UK-based Optimum Population Trust sells “population offsets” by which individuals and organizations ostensibly can “offset their carbon footprint” by funding family planning programs.
On Valentine’s Day, the Arizona-based Center for Biological Diversity gave away ten thousand “endangered species condoms” sporting slogans like “Wrap with care, save a polar bear.”
Voluntary family planning is a good thing in its own right. But condoms won’t save the polar bear.
Blaming climate change simply on human numbers is itself founded on denial – denial of the real causes of the problem and denial of our potential to forge positive solutions. It spreads demoralization and paralysis at a time when we need hope and activism.
In recent decades population growth rates have plummeted across the globe. In the Global South, the average number of children per woman is now 2.7 and it is predicted to fall to 2.1, the replacement level, by mid-century. In the meantime, in the poorest countries with the highest birth rates, consumption levels are so low that they contribute little or nothing to greenhouse gas emissions. In the Global North, where below-replacement fertility is now the norm, demographers worry mainly about the rising ratio of elderly to young people.
For most of human history, people did not pour greenhouse gases into the air. Climate fluctuations from natural causes were slow, and so people could adapt to them. This changed in the nineteenth century when we commenced burning fossil fuels – coal, oil, and natural gas – on a large scale. For the past six generations or so, we relied for much of our energy on poisonous stuff excavated from beneath the Earth’s surface. It is this crude technology – not human numbers – that drives climate change.
Blaming climate change on “people,” rather than on specific things done by specific people in specific times and places, puts Malthusian environmentalists in an uncomfortable position. After all, they’re people too. The psychological solution is to project blame onto others, while drawing comfort from the thought that they are the enlightened exceptions to the rule. This conceit feeds the greening of hate, the scapegoating of foreigners and immigrants for our environmental ills.
The people-as-problem message also undermines public receptivity to environmental truths. Most people do not appreciate being told that they are a cancer on the face of the Earth. The fact that nearly half of American adults do not believe that humans are causing climate change cannot be attributed solely to corporate propaganda and deficient education. It also reflects their desire for a worldview that is not based on self-loathing.
Instead of buying into the “more people = more emissions” equation, we should put the blame for climate change squarely where it belongs: on fossil fuels and the vested interests that seek to perpetuate dependence on them.
We also ought to give credit where credit is due, recognizing the positive innovations in energy efficiency and renewable energy, including smart-grid technologies to facilitate locally distributed power generation and green-power superhighways to lower the costs of transmitting wind and solar power over long distances. The clean-energy future is being created by people, too.

Truthout Is Preparing to Meet Trump’s Agenda With Resistance at Every Turn
Dear Truthout Community,
If you feel rage, despondency, confusion and deep fear today, you are not alone. We’re feeling it too. We are heartsick. Facing down Trump’s fascist agenda, we are desperately worried about the most vulnerable people among us, including our loved ones and everyone in the Truthout community, and our minds are racing a million miles a minute to try to map out all that needs to be done.
We must give ourselves space to grieve and feel our fear, feel our rage, and keep in the forefront of our mind the stark truth that millions of real human lives are on the line. And simultaneously, we’ve got to get to work, take stock of our resources, and prepare to throw ourselves full force into the movement.
Journalism is a linchpin of that movement. Even as we are reeling, we’re summoning up all the energy we can to face down what’s coming, because we know that one of the sharpest weapons against fascism is publishing the truth.
There are many terrifying planks to the Trump agenda, and we plan to devote ourselves to reporting thoroughly on each one and, crucially, covering the movements resisting them. We also recognize that Trump is a dire threat to journalism itself, and that we must take this seriously from the outset.
After the election, the four of us sat down to have some hard but necessary conversations about Truthout under a Trump presidency. How would we defend our publication from an avalanche of far right lawsuits that seek to bankrupt us? How would we keep our reporters safe if they need to cover outbreaks of political violence, or if they are targeted by authorities? How will we urgently produce the practical analysis, tools and movement coverage that you need right now — breaking through our normal routines to meet a terrifying moment in ways that best serve you?
It will be a tough, scary four years to produce social justice-driven journalism. We need to deliver news, strategy, liberatory ideas, tools and movement-sparking solutions with a force that we never have had to before. And at the same time, we desperately need to protect our ability to do so.
We know this is such a painful moment and donations may understandably be the last thing on your mind. But we must ask for your support, which is needed in a new and urgent way.
We promise we will kick into an even higher gear to give you truthful news that cuts against the disinformation and vitriol and hate and violence. We promise to publish analyses that will serve the needs of the movements we all rely on to survive the next four years, and even build for the future. We promise to be responsive, to recognize you as members of our community with a vital stake and voice in this work.
Please dig deep if you can, but a donation of any amount will be a truly meaningful and tangible action in this cataclysmic historical moment.
We’re with you. Let’s do all we can to move forward together.
With love, rage, and solidarity,
Maya, Negin, Saima, and Ziggy
