This is something I haven’t read about, a way to capture CO2 and use it and microbes to grow protein.

It says we exhale much of the carbon we eat. I started thinking about the possibility of someday we would wear a breathing apparatus that captures the CO2 we exhale and use something, possibly microbes, to fix it so it doesn’t get into the atmosphere. This could capture a more concentrated part of the CO2 we generate. The added benefit is that it would filter out the germs we exhale so that almost no diseases such as CoVID19 could be transmitted to other people.
