Based on data from the National Institute of Recyclers, a cardboard ticket takes a month to break down; a bamboo branch, from one to three months; a cotton towel, from one to five months; a woolen sock, a year; painted wood, a little over a year; a tin can, 100 months; an aluminum can, from 200 to 500 years; and a glass bottle, more than a million years.
Uuriti ka seda, kui tihti inimesed kirikus käivad. 39 protsenti küsitletutest ei käi jumalateenistustel kunagi või peaaegu mitte kunagi, 25 protsenti käib ainult pühade ajal ja 3 protsenti kord nädalas.
