Plant-Based Pet Diets Could Slash Environmental Impact by 1000%
A new study reveals that switching pets to plant-based diets could significantly reduce the environmental impact of the pet food sector. The research highlights the stark differences between meat-based and plant-based pet food, with the latter showing a much lower carbon footprint and reduced land and water usage.
The study, which focused on dry dog food in the UK, found that plant-based diets have impacts 14 to 16 times lower than beef-based feeds for eutrophication and acidifying effects. Lamb- and beef-based diets require over 37 times more land and produce over 10 times more CO2 than plant-based diets. Water extraction is also significantly higher for meat-based diets, with lamb and beef showing over 500 and 600 liters per 1000 kcals, compared to 249 liters for plant-based foods.
Feeding a dog a meat-heavy diet requires 57 football-fields' worth of land, while a plant-based diet requires only 1.4 fields. This means that shifting towards lower-impact pet food ingredients could significantly reduce the ecological paw print of the pet food sector. With almost 500 million pet dogs worldwide in 2018, this shift could have a substantial global impact, equivalent to reducing the emissions of a country like the Philippines.
The study underscores the environmental benefits of plant-based pet diets, which have the lowest environmental impact on every metric and are similarly nutritious to meat-focused diets. As pet owners become more aware of the environmental impact of their pets' food, the demand for sustainable, plant-based pet food options is expected to grow.
