[Coral-List] smoke from large ships now put into the water

[Douglas Fenner]

Shipping rule cleans the air but dirties the water

Ships used to use high-sulfur fuel oil because it is cheaper than
low-sulfur.  An international law gave them lots of time to switch, but
they didn't.  Now they have to reduce emissions.  The law allowed them to
use a "scrubber" on their smoke stacks, but the water used to scrub it out
of the smoke is released into the water.  So they continue to burn
high-sulfur fuel oil.

"The Great Barrier Reef, for example, receives about 32 million tons of
scrubber effluent per year because it's near a major shipping route for
coal."

Slashing emissions by 2050 isn't enough.  We can bring down temperature now.

Humans have destroyed 97% of earth's ecosystems
(well, more like only 3% are fully intact)

Study: One-third of plant and animal species could be gone in 50 years.
(but 2-4 times worse in tropics)
