How does cigeratte smoke effect nature?

Cigarettes are damaging our environment. Not the smoke but the butts that remain after they are smoked. Researchers estimate 1.7 million pounds of cigarette butts accumulate in lakes and oceans and on beaches and the rest of the planet every year. They contain dangerous chemicals including carcinogens and other poisons. Cigarette butts are not biodegradable, so they remain in the sewers for a long time and contaminate the water.
