#AI is already shaping the future of animals—and if it runs factory farms, billions of lives could be controlled by these systems.

Is Eating Animals (Always) Wrong?
Is Eating Animals (Always) Wrong? YouTube video by Jack Symes | Philosophy

I recently sat down for an interview with Jack Symes.

We discuss why animal suffering matters morally, whether speciesism is comparable to racism, and examine thought experiments to test our intuitions.

I was privileged to know Jane Goodall, and even to have some influence on the extension of her concern from chimpanzees and other free-living animals to animals confined in factory farms. I'm pleased that there will be a series of panels honouring her life and legacy.

The Responsibility to Protect and the War Against Iran Peter Singer & Savita Pawnday rebut the view that the United Nations-endorsed R2P doctrine cleared a legal path to the US-Israeli airstrikes.

In my new Project Syndicate article, co-authored with Savita Pawnday, we explain why the idea, adopted by the UN, that there is an international Responsibility to Protect cannot be used to justify the war on Iran.

R2P was meant to prevent atrocities, not to provide cover for military intervention.

Can AI systems weigh interests impartially or do they simply reflect our own flawed judgments at scale?

I recently spoke with Human Layer AI about whether artificial intelligence can make moral decisions. Utilitarians should like that if AI is better at impartially maximising the well-being of all. But when we try to build utilitarian reasoning into machines, things can go wrong. We discuss...

He suggests we should begin by asking “what the world needs” and “what sorts of person and aptitudes are most needed,” and then consider where we might fit.
In some cases, that may mean working directly on a problem. In others, it could mean earning more in order to give more.

Semaglutide is going off-patent in India. But will people who need it be able to get it? Rules determining who gets access to semaglutide in India were written for different bodies with different cardiovascular risks.

If access depends on flawed metrics, those who need treatment most may still miss out.

I explore the ethical implications in this piece, co-authored with Dr Aditi Kantipuly.

Semaglutide is going off-patent in India. That should make it cheaper and more widely available. But a deeper question remains: who actually gets access?

In countries like India, using BMI alone to determine eligibility risks excluding many people who face serious health risks at lower thresholds.

In a globalised world, everything we eat, wear, and use has impacts. Zoe’s suggestion is straightforward: inquire into the effects of your choices and ask whether they align with your values. That, she argues, is how we begin to live with integrity.

The Troubling Ethics of Crowdfunding Peter Singer & Gregory E. Pence describe the many problems, from systemic bias to fraud, associated with platforms like GoFundMe.

Campaigns often reward those who are most visible, most connected, or best able to tell a compelling story, rather than those whose needs are greatest.

Her approach is simple: roll up your sleeves and get to work. The hope may return. And if it doesn’t, there is still work to be done, and meaning to be found in doing it.

Zoe made a point that struck me. Hope, she says, is an emotion. It comes and goes. What matters more is whether, when you look in the mirror, you can respect the person you’re looking at.

In the U.S., tens of millions of chickens and turkeys on factory farms have been killed in the last few years by being deliberately heated to death. It takes them hours to die.
This unbelievably cruel method is legal everywhere in the US. Now Colorado might become the first state to ban it.

As she puts it, the real question is not whether optimism is justified, but what we choose to do with our time.

Her answer is simple: keep pushing toward a “North Star,” continuing to work for a more just, humane, and sustainable world, even when the outlook is uncertain.
