Thinning Arctic ice driving mercury pollution: NASA

The video discusses how climate change affects Arctic ice, leading to mercury pollution. A NASA report explains that sunlight reacting with salt in ice produces bromine, which destroys ozone and triggers a bromine explosion. This process creates bromine monoxide, which reacts with gaseous mercury, causing it to fall to Earth and accumulate in fish.
