How Vancouver is protecting itself from future flooding — with plants

Large cities like Vacounver and Seattle are increasingly leaning towards "green infrastracture," a method of managing stormwater through natural systems like green roofs and rain gardens that absorb rainwater. Cities have traditionally relied on traditional sewage systems, but in the face of climate change, and more intense storms, its proving to be inadequate. Green infrascture lowers flood levels, filters out pollutants in the water, and regulates city temperature. In Seattle, an early adopter of green infrastructure, rain gardens absorbed 1.5 trillion liters of rainwate.
