"Massive Seaweed Blob Threatens Florida's Beaches and Tourism Industry"

A giant seaweed bloom, twice the size of the continental United States, is heading towards Florida and other coastlines in the Gulf of Mexico, threatening to dump smelly and possibly harmful piles across beaches and dampening tourism season. Sargassum, the specific variety of seaweed, can be beneficial for ocean life when adrift at sea, but when it hits the beaches, it can emit a gas that smells like rotten eggs and suck the oxygen out of the water, creating dead zones. The seaweed can also be dangerous to humans, emitting toxic gas and containing arsenic in its flesh.
