After that, the current pushes them to the north through the Atlantic Sea and makes them multiply very quickly, in order to later end up on the beaches.

Although Sargassum can benefit some marine animals, as it is also a refuge for some species such as fish, crabs and sea turtles, It can affect ecosystems.

Likewise, the experts cited New York times They add that When sargassum rots, it pollutes the water by releasing hydrogen sulfide, a colorless gas that can cause respiratory problems in humans.. For his part, Lapointe, a research professor at Florida Atlantic University, added that since these macroalgae contain arsenic, they can find their way into the food chain if they are used in some fertilizers.

In 2018, doctors in the Caribbean islands of Guadeloupe and Martinique reported some health harms. it seems, The effects of sargassum have caused thousands of “acute” exposures to hydrogen sulfide. This year, it will be in Caribbean waters until mid-October.
