Farm animal welfare at TED

Lewis Bollard, Program Director of Farm Animal Welfare at Open Philanthropy, gave the first-ever mainstage TED talk on factory farming. He focused on three tragic practices: gestation crates for pregnant pigs, battery cages for egg-laying hens, and the slaughter of male chicks. Instead of asking his audience to go vegan, he asked them to talk about factory farming. Why? 

Bollard writes: “as society-wide solutions, I think [going vegan, or eating pasture-raised meat] have largely failed. That’s through no fault of their advocates. Almost all efforts at permanent consumer boycotts — whether of blood diamonds, sweatshop clothing, or palm oil — have met a similar fate.”

Most people (Bollard cites an 88% figure from a US survey in his talk) think that gestation crates and battery cages are unacceptable. But we don’t talk about it. Perhaps because most people don’t support it, and taking that fact seriously would mean becoming vegan, donating or advocating, we mostly avoid even thinking about it. That’s why, when speaking to a very broad audience, Bollard attempted to make factory farming a more mainstream topic of discussion. 

Specifically, he asked the audience to: “Tell the corporations you buy from, the politicians you vote for, that you expect them to adopt basic, common-sense policies to end the worst practices. And tell everyone what you’ve learned about factory farming.”

If you’re in the UK and want to take him up on this, consider taking part in the mass lobby day. Lewis wrote up some other next steps here


 

 

 

SB 53: another crack at regulating AI

 
On September 29th last year, California Governor Newsom vetoed SB 1047, the first piece of AI safety legislation in the state, and one which, if successful, would have had an international impact. Now, SB 53, a less transformative but overall similar bill, is on its way through the California Senate

Though most of you readers aren’t in California, the leading AI companies are. How California chooses to regulate its AI companies affects all of us. SB 53 would require the leading AI companies to publish safety policies, and then to follow them (currently, this is voluntary). It would expand whistleblower protections, allowing staff and external contractors to report safety breaches. 

If the bill passes, would it protect us from existential risks? Celia Ford of Transformer thinks it “likely isn’t strong enough”. On the other hand, this would be a start, allowing some semblance of oversight over AI systems and companies that are only getting more powerful.

Andrés Jiménez Zorrilla — featured person

  
I’m experimenting with featuring a person each month, alongside the news. As always, you can give feedback here

Until 2018, Andrés Jiménez Zorrilla worked in finance. 

“At first, the financial rewards made me not care about many other things,” Andrés recalls in an interview. “But over time, I couldn’t ignore the fact that I was just making rich people richer. It didn’t feel like my calling.”

After a year of disappointing volunteering at NGOs and searching for opportunities, Andrés’ wife sent him a link to Ambitious Impact’s charity entrepreneurship programme (which, incidentally, is open again now). 

Andrés read introductory effective altruism texts and found that "It was a really exciting new way of looking at how to proactively improve the world." He was accepted into the charity entrepreneurship programme and, to his surprise, ended up founding the Shrimp Welfare Project with co-founder Aaron Boddy. 

“When I first read about the concept of shrimp welfare, I thought that effective altruists had taken their logical conclusions to a crazy extreme.” He said, “But there were half a trillion shrimp out there, there was some evidence that they could experience suffering, and there were zero people working on this.” 

Nowadays, the Shrimp Welfare Project estimates it helps billion shrimp annually.

Timeless Classic


With the publication of Essays on Longtermism, it’s a great time to share Hilary Greaves and William MacAskill’s paper ‘The Case for Strong Longtermism’. Now a published chapter, various working versions of this paper have been bouncing around for years. 

The argument is a detailed, well-honed case for “strong longtermism: the view that impact on the far future is the most important feature of our actions today”. The strong longtermist claim (whether interpreted as axiological — a claim about what is valuable — or deontic — a claim about what we should do) has been provoking to many. Like Peter Singer’s drowning child argument, if true, it may ask us to drastically change how we act and what we value. For anyone looking to do the best they can with their lives, it’s a philosophical idea worth grappling with. (And, perhaps, responding to as part of our essay competition.)
