Sustainable Pet Diets: A Leading Effective Altruism Issue

Le résumé fourni par la source

While animal-derived ingredients continue to dominate pet food, mounting animal welfare and environmental pressures are starting to reshape the market-opening the door to plant-based and cultivated meat alternatives for dogs and cats. This study assessed the effective altruism case for more sustainable pet food options, using the scale, neglectedness, and tractability framework, and found strong alignment across all three dimensions. By 2018, at least 9% of farmed land animals were fed to companion dogs and cats globally, with more consumed by average dogs (13) than by average people (9) annually. A global transition to nutritionally sound vegan pet diets could spare seven billion farmed land animals and many billions of marine animals from slaughter and could feed 519 million additional people using food energy savings. Such a transition for dogs alone could eliminate 1.5 times the quantity of greenhouse gases produced annually by the UK and free up land larger than Mexico. Yet, sustainable pet food is a highly neglected issue in terms of funding, time, and talent. The issue appears tractable; 13-18% of dog and cat guardians would consider vegan pet diets if their concerns about them were addressed. Assuming only one dog or cat per guardian, at least 70 million dogs and 86 million cats worldwide could potentially be transitioned to vegan diets, with the true figures probably several times higher. Sustainable pet diets, therefore, represent a highly impactful yet overlooked opportunity to reduce farmed animal consumption, mitigate associated environmental impacts, and improve food security.
