Two photos from the same location. The coasts along central- and South America have been experiencing a massive growth of Sargassum, which cause the beaches to look like the second photo rather than the first one. Sargassum is a toxic form of seaweed, which contains a lot of heavy metals such as lead, mercury etc. This used to be a problem for a couple of weeks a year, but now it’s happening for almost 5-6 months every year, and is doing great damage to the tourism in countries that absolutely depend on this. This is happening due to climate changes, that makes the water warmer, and changes the currents. This was horrible to see, and made me realize that we need to do something now! Because there’s no planet B!
