In the US, there are more than 163 million dogs and cats that consume, as a significant portion of their diet, animal products and therefore potentially constitute a considerable dietary footprint.

Here, the energy and animal-derived product consumption of these pets in the US is evaluated for the first time, as are the environmental impacts from the animal products fed to them, including feces production. In the US, dogs and cats consume about 19% ± 2% of the amount of dietary energy that humans do (203 ± 15 PJ yr-1 vs. 1051 ± 9 PJ yr-1) and 33% ± 9% of the animal-derived energy (67 ± 17 PJ yr-1 vs. 206 ± 2 PJ yr-1). They produce about 30% ± 13%, by mass, as much feces as Americans (5.1 ± Tg yr-1 vs. 17.2 Tg yr-1), and through their diet, constitute about 25–30% of the environmental impacts from animal production in terms of the use of land, water, fossil fuel, phosphate, and biocides.

Dog and cat animal product consumption is responsible for release of up to 64 ± 16 million tons CO2-equivalent methane and nitrous oxide, two powerful greenhouse gasses (GHGs). Americans are the largest pet owners in the world, but the tradition of pet ownership in the US has considerable costs. As pet ownership increases in some developing countries, especially China, and trends continue in pet food toward higher content and quality of meat, globally, pet ownership will compound the environmental impacts

How much? — “13.6 million cars driving for a year.” What else, via MIT: Vast areas of South Asia – covering 75% of the area’s population – would endure at least one heatwave of 31C WBT. This is already above the level deemed by the US National Weather Service to represent “extreme danger”, with its warning stating: “If you don’t take precautions immediately when conditions are extreme, you may become seriously ill or even die.” — Doomed, Doomed!!!

Of course you could put on a hat, sit in the shade, chill out with a nice iced tea and spend 5 minutes with another view from MIT. Oh yeah, turn on the AC too.
