The article cites statistics by the Environmental Protection Agency stating Americans dump 4.6 pounds of garbage per person per day and food waste accounts for about 13 percent of total trash nationally.
All this trash eventually ends up in landfills. So to avoid making so much trash people are recycling and composting everything possible.
The Times article indicates the hardest part of composting is educating those who have no clue what it’s all about. But the photo above, which was taken by frankfarm and obtained via Flickr, shows how UC San Francisco is taking up the issue of composting. Notice how they visually show students what goes where.
