after a coal mine shuts down the
pollution doesn't stop
toxic waste flows for decades
contaminating rivers and killing aquatic
life
now a team has developed a method to
harvest the muck
and turn it
into paint
the team dries the pigment before
shipping it off to a giant kiln
they change the color by controlling the
temperature
for now true pigments can't harvest
enough iron oxide to clean up an entire
stream
these mines will continue producing amd
for hundreds of years but michelle is
confident that turning pollution into
art can make a difference
