Quagga mussels have totally hijacked Lake Geneva, clogging up pipes, wrecking cooling systems, and even threatening research labs and airports. These tiny invaders breed like crazy—one female can lay a million eggs! Now, the lake’s ecosystem is flipped: native species are gone, and the water’s so clear it’s messing with the whole food chain. Locals can’t even walk barefoot on the beach anymore. Scientists say there’s no going back—Lake Geneva is forever changed. #Science #LakeGeneva #InvasiveSpecies
