Live near the ocean? Ever wonder why your air is so clean, while the poor saps inland keep dying from smog? Reuters reports salty sea spray actually scrubs out air pollution. According to an article published in the journal Science, some of the spray rises high into the atmosphere and helps create raindrops, which drag pollution back down to earth (they also make you wet when it rains.) “The idea that larger salt particles can seed clouds and enhance rainfall is not new but it was not combined with actual observation,” says Daniel Rosenfeld, who conducted the experiment.
