The sargassum bloom, at around 5,000 miles wide, is twice the width of the United States and is believed to be the largest in history.
Drifting between the Atlantic coast of Africa and the Gulf of Mexico, the thick mat of algae can provide a habitat for marine life and absorb carbon dioxide.
However, the giant bloom can have disastrous consequences as it gets closer to the shore. Coral, for instance, can be deprived of sunlight.
