Eric Peterson Posted about 3 years ago Why do we have so much garbage, & what can/should be done to reduce it? Composting and recycling can eliminate a large percent of garbage in an efficient manner, but many people are not willing to do it. Much of the food that is thrown out can be composted and much of the paper, plastic, and metals can be recycled. Perhaps effort should be made to make composting more accessible to people in the city.In addition, there are often reusable substitutes, such as cloth napkins and rags. It also is important to ensure that that externalities are compensated for with government policies, so perhaps garbage disposal should be taxed according to its environmental impact. Advocacy may also help.
