I can’t believe that disposable diapers are any less polluting to the environment than plastic straws. Like many so-called biodegradable wipes, they don’t actually disintegrate over a period of time. I used cloth diapers for both my sons, one born in 1966, and the other in 1971.
Yes, I remember seeing (long ago) a documentary about non-biodegradables in landfills.
The plastic in disposable diapers & garbage bags just seethes & bubbles on the soil like some kind of writhing monster that won’t die.
