In summary, there are two important reasons why I believe it’s more important to direct additional resources towards animal welfare over global health:

1. Global health and human welfare are generally improving whilst animal suffering is getting worse at a worrying (and potentially accelerating) rate. For factory farming, the default is it gets worse and worse over the next 50 years. In my view, it’s still unclear if we’ll end factory farming and we’re competing with a very powerful incumbent industry to make it happen. I don’t believe the same trajectory is true for global health.
2. Animal welfare is orders of magnitude more neglected on most important metrics: Philanthropic funding, government funding or great people working on the issue.

These reasons aren’t necessarily all that is required to think it would be better to spend an additional $100M on animal welfare relative to global health (see the 80,000 Hours profile on factory farming for a more comprehensive overview) but they’re notable for me. They’re also part of the main reason I stopped working on things to improve human welfare (via tackling climate change) to focus my efforts on animal welfare. 

1. Global health is progressing whilst animal suffering rapidly increases

Our World in Data has some great information about changes in important metrics and numbers over time. If you scour the website, you’ll see that for most (not all) human welfare-related metrics, things are improving. Whether it’s the share of people in poverty, child mortality, life expectancy, income or some of the other metrics listed below, things are generally going in a positive direction.  

This should be cause for celebration – the human condition is improving. We’re managing to live longer and healthier lives, be richer, and generally reduce the death rate of infectious diseases (except when struck by a pandemic).

However, the charts look very different when thinking about animal welfare. On almost every major metric, things are getting rapidly worse. For example, there is a worrying rise in the number of land animals killed for meat per year. 

The FAO also predicts that meat consumption will grow by 40% by 2050 relative to 2020 levels, showing that increased suffering for farmed animals is our default trajectory.

Sadly, this trend isn’t limited to terrestrial animals. Aquatic animals, farmed in the hundreds of billions, follow the same trend. The below graph shows the number of farmed fish globally and the numbers for farmed shrimp are even higher, estimated to be around 440 billion (!) per year. These numbers are hard to comprehend, but it’s important to try. 

Of course, there may be doubts about sentience for these animals. I won’t make that case here as much smarter people than me have done so – see the Rethink Priorities work here on Welfare Ranges or Jonathan Birch et al. on decapod crustaceans (which influenced UK legislation on this issue).

What is important is that the most important number for farmed animal welfare, the number of farmed animals suffering, is increasing year-on-year, with no signs of plateauing.

Sadly, it gets worse. At least in the case of climate change, where emissions are still (relatively very slowly) increasing, there is a rapid growth in climate change-mitigating technologies. Renewable energy (one of the key solutions to climate change) is experiencing enormous growth, indicating that displacement and a reduction in greenhouse gases are fairly imminent. 

Consumption of plant-based meats and alternative proteins (the renewables of the farmed animal movement) are in a much worse place. You would think the private sector might have this covered but that is far from the case:

• Sales for the plant-based sector have flat-lined, with no clear mass-market adoption of plant-based meats.
• Cultivated meat has already been banned in Italy, Alabama and Florida, with additional interest in doing so from Hungary, Austria, other US states and maybe even the entire EU.
• Investment in the sector has also dried up – GFI estimates that alternative protein investment in 2023 was about 28% of what it was in 2021. As a result, many companies have been or will be forced to close or merge. 

It isn’t all bad (see Lewis Bollard’s newsletter on some of his hopes for the industry) but it does signal that left purely to market forces, alternative proteins will likely not displace significant (e.g. 20%+) amounts of meat consumption anytime soon. 

Note: The chart above shows things cumulatively, likely to avoid the bad look of having rapidly shrinking investment in the most recent two years. But make no mistake, $5.6B to $1.6B is a huge drop in investment for alternative proteins.

Additionally, the percentage of vegans/vegetarians, even in our most successful advocacy countries, also shows a worrying picture. There has been basically no more than a 1.5 percentage point increase in the population of veganism and vegetarianism over the past 20 years.

(I’ll be honest, I barely know what is happening in that last graph but focus on the red dotted line which is the author’s best guess where he aggregates several different polls). 

That’s probably enough graphs – I think you get the point. Long story short: Whilst there are some glimmers of progress around the world, we’re losing the war.

In my opinion, this makes it all the more important to work on farmed animal advocacy. The current trajectory of society is a huge increase in animal suffering over the next few decades, as the human population continues to increase, many countries become richer and eat more meat and factory farming spreads to less developed countries. As such, the opportunity for counterfactual impact is huge – we have an opportunity to act now to avert untold suffering.

In contrast, I expect that we will, without additional funds, significantly improve global health outcomes over the next 80 years, as has been the trend shown by the graphs above. There is almost no coordinated opposition to this issue, there is mainstream public and governmental support and many resources dedicated to it (see below).

(Someone here might say that tackling farmed animal welfare must be intractable then – why should we bother? I don’t think it is, and we do have plenty of success stories, but what we need is more great people, funding and broader support. More on that below.)

Orders of magnitude less resources go towards animal welfare

The second crucial reason why I think diverting additional money and people to work on animal welfare is due to the scale of neglectedness.

In terms of philanthropic funding, the entirety of the farmed animal welfare movement uses approximately $290 million each year. For reference, the climate movement absorbs around $10.3 billion in philanthropic funding and that number is $11 billion for global development. That is a 30x different in size. 

Of this, two entities make up approximately 50% of all funding (one of them being Open Philanthropy), showing the potential significance of additional major donors in both diversification and increasing the total amount of funding. 

As a grantmaker working in farmed animal welfare, I see first-hand that there are a number of great ideas, strong teams and innovative projects that would achieve significant impact for animals if they weren’t so constrained by money. In addition, farmed animal donors regularly have to turn down proposals that are likely key aspects of ending factory farming but we can’t fund them due those projects being too large to justify with current funding amounts.

Note: I used global development funding, rather than global health, as it was slightly easier to find reliable numbers. I included climate change numbers for additional context on how uniquely small the farmed animal welfare movement is. 

Sadly, the numbers are similar when thinking about government (rather than philanthropic) spending across the same issues. Here I used data on government alternative protein investment as I couldn’t find anything useful for government spending on farmed animal welfare. Even if I did, I wouldn’t expect the chart to change much, if at all. Again, this means that governments spend 440x more on global development relative to alternative proteins (and farmed animal welfare).

Finally, let’s think about people. 80,000 Hours estimates that there are 1,750 - 2,000 people working full-time in the nonprofit sector to help farmed animals. Assuming the money-to-people ratio is the same for global development, that means there are around 75,000 people working in the nonprofit global development space. In my view, this alone makes it clear that attracting talented people can have much greater marginal returns in farmed animal welfare relative to global health and development.

However, I think there is a much smaller group of people who are really “leading” the farmed animal advocacy movement. And I think it’s worrying that I can likely name most of them off the top of my head, because of how small we are. This to me drills home how important it is to have a few additional great people – imagine what we could an additional Carolina Galvani, Mahi Klosterhalfen or Ryan Xue.
