A new study reports that cigarette butt litter harms plant development.
The left-over of cigarettes dropped in grass and soil could cut down the germination, or development, of plants.
According to the study, about 5.6 trillion cigarettes are manufactured worldwide each year, and nearly 4.5 trillion butts are littered each year globally.
The most common ingredient used in cigarettes filters is Cellulose Acetate, which is hazardous to the environment.
A sample of 128 discarded cigarettes butts per square meter was taken in the city of Cambridge. It resulted that there was no difference between the harm caused by smoked cigarettes and unsmoked cigarettes.
Environmental activists are in favor of banning cigarette filters. Cigarette smoke is also harmful to the environment
