How long does it take for the common garbage to decompose?
They really stay longer than we think! According to this site:
banana peel: 3-4 weeks
paper bag: 1 month
wool sock: 1 year
leather shoe: 45 years
tin can: 90 years
aluminum can: 200-500 years
disposable diaper: 550 years
plastic jug: 1 million years
styrofoam (polystyrene?) container: more than 1 million years
I also found different results in other sites, but this sums up the idea. Wow, a lot of our garbage last more than our lifetime! Consume less, and we make a huge difference. Coffee in foam cup doesn’t sound appealing anyway.
