Negotiators fail to reach an agreement on plastic pollution treaty

In Ghana, communities, bodies of water, drains and farmlands are choked with plastics,

Why don't the local people simply pick it and collect it somewhere? In most of the developing countries I've been to, I routinely saw discarded plastic debris strewn all over the place, most of it in places like beachs and fields where it could easliy picked up and collected. But the local people don't seem to care, and toss their garbage wherever they feel.

I guess it's easier for the developing countries to blame the developed world than take some initiatives at their grass roots level.
