Many many times. Dumpster diving feeds people. Ash trays provide a smoke. In the USA we are so wasteful whole subcultures survive of our throw aways.
Ones garbage is another man's treasure.
We should reframe our consciousness to think of the waste as being what is disgusting and not the consumption of it.
If a wealthy man smokes half of his cigarrette and puts in out. Half will go into landfill or runoff water. If a poor man smokes the remainder nothing gets placed in our environment.
Who is the better man?
