Recently, in the middle of the Atlantic Ocean, there is a “seaweed blob” that has formed, and it has worried some people that it will end up on Florida’s beaches and other beaches along the Gulf of Mexico coastline.

The blob, composed of sargassum seaweed, began forming in 2011. Now, it has grown to be twice the width of the continental United States, according to a CNN article.

A massive amount of seaweed started to float up to shore and at one point was so dense that the width at some points was more than 3 feet thick, which was making people stay away from the beach.

It was formed from a large amount of seaweed that got tangled together and then floated around and collected more seaweed and is now floating towards Florida and could disrupt tourists’ summer travel plans.

Why is there so much seaweed? Well, since the climate is getting warmer and warmer, more nutrients are available resulting in an increase in seaweed growth.

The seaweed blob is estimated to arrive in Florida some time in May and last a few months until somewhere around October. Florida is preparing for it and already planning for twice-daily cleanings.
