Farming algae could surprisingly help stave off deadly algae blooms If you can't beat them... sow them? In water? Could work. A A Reset One possible solution to nutrient pollution and dangerous algal blooms could be seaweed farms, a new paper reports.

Marine ecosystems especially suffer from nutrient pollution, as most of our waste tends to get dumped in the sea. This kind of pollution can become very deadly, as high levels of nutrients foster algal blooms which destroy water quality and deplete its oxygen — in short, they kill everything else around them.
