These add to Google’s existing sustainability efforts. From 2017 to 2018, it cut its product shipment carbon emissions by 40 percent. Its Power Project will provide one million energy-saving Nest thermostats to families in need by 2023, and many Nest products are already made with post-consumer recycled plastic.

Switching to recycled content isn’t always easy, though. As Fast Company reports, when Google’s hardware team began working on a yet-to-be-announced product that will be out later this year, it decided to swap industry-standard polyester fabric for fabric made from recycled bottles. It reportedly took the team two years to make sure the material met design and manufacturing requirements and that vendors could supply it at scale. Now, each unit of the mystery product will reuse a third of a plastic bottle. That’s the kind of thing we may see more frequently beginning in 2022.

The study estimates that annual microplastic consumption ranges from 39,000 to 52,000 particles, from food sources alone. When you factor in the microplastics Americans inhale, the numbers jump to 74,000 and 121,000. Americans who drink exclusively from plastic water bottles may be ingesting an additional 90,000 microplastics annually, which at the very least should be another reason to stop buying plastic water bottles. The researchers admit these are rough estimates, but if anything, they are “likely drastic underestimates.”

A team of biologists from the University of Victoria in Canada conducted the study. They looked at microplastics in commonly consumed foods — seafood, sugars, salts, honey — as well as alcohol, tap water, bottled water and urban air. The researchers note that the microplastic content of poultry, beef, dairy, grains and vegetables has not been studied. We don’t know how much plastic we might ingest from food packaging, either.

According to the study, microplastics are “ubiquitous across ecosystems.” We knew the ocean was full of plastic, but the researchers suggests our bodies might also be packed with plastic. While there is potential for microplastics to enter human tissue — which might cause an immune response or release toxic chemicals into the body — we don’t fully understand how microplastics impact humans, at least not yet.
