Because someone says they are biodegradable smokers think they can throw them on the ground.
It takes 3 to 15 years for one C Butt to biodegrade depending on where it happens to be in the environment when and where it eventually settles and makes its gross home to sit there and stink.

Switch to non filters ftw please.
