Day after day, you pump carbon dioxide into the atmosphere, whether you’re driving or turning on lights or eating meat. You can’t help it, because, really, no human can. But I bet you haven’t stopped to think about how the simple act of pooping is also part of the problem: Worldwide, wastewater treatment facilities account for 3 percent of electricity consumption and contribute 1.6 percent of emissions.
A drop in the horrifying bucket that is climate change, you might say. But researchers are beginning to explore how we might tweak wastewater treatment technology to capture CO2 instead of emitting it, as a way to slow the ravages of climate change. If their plan works out, at least our poop can be guilt-free.
