but it is blue carbon. (laughing) - right. (jayda): so the "blue" in "blue carbon" is because this process is taking place under water, and that is the key. because in wet, swampy mud where there's little oxygen, the carbon can be safely stored away for millennia. it's wild to me that for so long, we have not given enough importance... - right. - ...to these kind of areas. and here we are in a climate crisis, and we're now holding on to these ecosystems for dear life, essentially. - yeah, yeah.
