And of course, these tailings ponds -- well, you can't see many ponds from outer space and you can see these, so maybe we should stop calling them ponds -- these massive toxic wastelands are built unlined and on the banks of the Athabasca River.
E, por suposto, estas  balsas de residuos, non se poden ver moitas balsas desde o espazo exterior e poden ver estas, así que quizais deberiamos parar de chamarlles balsas, estes enormes ermos tóxicos son construídos sen regras nas beiras do río Athabasca.
