True. Every time I see someone chuck their butt, I shake my head. So many folks don't realize the filters are plastic-- great that you made this post. BUT... there is a solution! My smoking friends now Ecobrick their butts. Over here in Indonesia, plastic pollution of all kinds is a massive problem. My team and I are working super hard developing and disseminating a super simple, open source technology called Ecobricks. Pack the butt! Check it out: www.Ecobricks.org I am just getting going on Steemit and can't wait to post more on this. :-)
