Ecosystem Dynamics and the Consequences of Intervening

Elephants in chains at travelling circuses; pregnant pigs trapped in coffin sized crates at factory farms; deers living in the wild. We should welcome the last as a pleasant break from the horror, right?

Maybe, but maybe not. While we tend to have a romanticised view of nature, life in the wild includes a range of extremely negative experiences.

Many animals are hunted by predators, and constantly have to remain vigilant about the risk of being killed, and perhaps experiencing the horror of being eaten alive. Resource competition often leads to chronic hunger or starvation. Their diseases and injuries are never treated. In winter animals freeze to death; in droughts they die of heat or thirst.

There are fewer than 20 people in the world dedicating their lives to researching these problems.

But according to Persis Eskander, researcher at the Open Philanthropy Project, if we sum up the negative experiences of all wild animals, their sheer number could make the scale of the problem larger than most other near-term concerns.

Persis urges us to recognise that nature isn’t inherently good or bad, but rather the result of an amoral evolutionary process. For those that can't survive the brutal indifference of their environment, life is often a series of bad experiences, followed by an even worse death.

But should we actually intervene? How do we know what animals are sentient? How often do animals feel hunger, cold, fear, happiness, satisfaction, boredom, and intense agony? Are there long-term technologies that could eventually allow us to massively improve wild animal welfare?

For most of these big questions, the answer is: we don’t know. And Persis thinks we're far away from knowing enough to start interfering with ecosystems. But that's all the more reason to start looking at these questions.

There are some concrete steps we could take today, like improving the way wild caught fish are slaughtered. Fish might lack the charisma of a lion or the intelligence of a pig, but if they have the capacity to suffer — and evidence suggests that they do — we should be thinking of ways to kill them painlessly rather than allowing them to suffocate to death over hours.

In today’s interview we explore wild animal welfare as a new field of research, and discuss:

• Do we have a moral duty towards wild animals or not?
• How should we measure the number of wild animals?
• What are some key activities that generate a lot of suffering or pleasure for wild animals that people might not fully appreciate?
• Is there a danger in imagining how we as humans would feel if we were put into their situation?
• Should we eliminate parasites and predators?
• How important are insects?
• How strongly should we focus on just avoiding humans going in and making things worse?
• How does this compare to work on farmed animal suffering?
• The most compelling arguments for humanity not dedicating resources to wild animal welfare
• Is there much of a case for the idea that this work could improve the very long-term future of humanity?

Rob is then joined by two of his colleagues — Niel Bowerman and Michelle Hutchinson — to quickly discuss:

• The importance of figuring out your values
• Chemistry, psychology, and other different paths towards working on wild animal welfare
• How to break into new fields
