The world’s mightiest waterway, the Amazon River, is threatened by the most diminutive of foes — a tiny mussel invading from China.
Since hitching its way to South America in the early 1990s, the golden mussel has claimed new territory at alarming speeds, plowing through indigenous flora and fauna as it has spread to waters in five countries. Now, scientists fear the invasive species could make a jump into the Amazon, threatening one of the world’s unique ecological systems.
“There’s no doubt the environmental effect would be dramatic,” said Marcia Divina de Olivieira, a scientist with the Brazilian government’s Embrapa research agency.
