Men removing water hyacinth, Eichhornia crassipes, from lake. It's an aquatic plant native to the Amazon basin, and a highly problematic invasive species outside its native range. When not controlled, water hyacinth will cover lakes and ponds entirely; this dramatically affects water flow, blocks sunlight from reaching native aquatic plants, which often die. Tejo (Tagus) river, Portugal
