Is a cigarette really considered "litter" though? They are biodegradable (after some time anyway).
The cigarette is biodegrable EXCEPT the part you throw out the window. Tobacco will degrade, as well as the paper wrapper, but the plastic filter is not.. or at least not within several years time.. ON top of that over 2.1 BILLION pounds of them are discarded on roadsides around the world every year. So before this years batch of cigarette butts 'degrade' they've been joined by about a 10 - 20 BILLION pounds of additional butts.
Arounds here you'd think they degraded because they DO disappear.. into the drainage grates, and into the Bay..
AND if I remember correctly a used cigaretter filter is actually poisonous.. the chemicals from the cigarettes are so highly saturated in the filter that the filter can be deadly to children and small animals if ingested.
PS.. PM Vrai about further information.
