Americans alone produced over 250 million tons of garbage. One large component of this waste consisted of oil based plastic bags, which are utilized excessively by grocers, restaurants, and stores nationwide. In order to reduce this source of waste, many countries are banning plastic bags or taxing customers for their use. Using at least two scholarly or reputable resources and your textbook, discuss at least two environmental problems caused by such extensive plastic bag use.
