#TheBahamas, March 17, 2023 – “If you don’t like it, go to another beach!” Is what Aaron John, an Education Officer from The Bahamas National Trust jokingly tells our news team about sargassum blooms; his quip, motivated by the necessity of nature when pit against the notion that there is a real threat when the stinky seaweed makes its annual appearance.
John can admit, he says, that Sargassum isn’t very pretty but life isn’t all about aesthetics and in this instance that ugly patch serves a purpose.
“We love our sandy beaches, but in order to keep them we need Sargassum. When storms come, they wash away all the sand off the beach but sargassum acts as a mulch to protect the sand from water erosion. It doesn’t look good, it
He said it also provides a habitat for small crustaceans, crabs, and insects that are all necessary to our ecosystem and islanders have found use for the weed.
“Historically, (in The Bahamas) we have been using sargassum as fertilizer, especially in the family Islands as far back as I know,” he said. “Birds don’t go on the beach unless there is Sargassum and what do they do? they feed – it’s beautiful.”
He encouraged residents to just leave it be if they came across it.
Sargassum isn’t harmful to humans, except for people with respiratory issues who may find the rotten egg smell triggers asthma. Despite this, it’s not advisable to walk through the weeds which may hide sharp rocks and bottles or vulnerable animals.
Experts say Sargassum blooms began to increase in size around 2011 and have continued to get bigger and bigger since. This year‘s bloom is around 5000 miles long and 300 miles wide and visible from space.
“I know it’s not a general outlook, but I would like to change the perspective on sargassum,” John said, pointing out The Bahamas National Trust is actively working to decrease alarm over the less worrisome events like sargassum as it raises the profile on the environmentally devastating.
