Without Blue There Is No Green

One of the best stories I heard recently
is the monetising of the recycling of fishing nets
across the world. There the poor retrieve them
from the seas where they damage wildlife
whilst ceasing to be of any service to fishermen.

There the poor exchange the waste nets for hard cash
which sustains hard pressed poorer communities.
After that the nets go on to become carpet tiling
of a very distinctive hue. Read more about it here.
