From an earlier evidence blog of mine on water, this issue came up. It would be a great topic for an EVOKE.
My responding blog was....
"We should have an entire EVOKE for garbage/waste management. So many communities are effected by a lack of disposal and others are creating a mess by producing more waste then necessary(lack of recycling).
Slums in many major cities through out the world have a slums area filled to capacity with waste."
