It sounds like a simple plan: redirect excess river water to deserts. But this plan potentially addresses a whole web of environmental problems including deforestation, dirty rivers, carbon emissions, rising sea levels and more.
The International Water Grid (IWG) is an under-ocean grid system constructed primarily of plastic pipes that will link rivers around the world to desert coastlines. From there, land distribution pipes and storage reservoirs will provide water sources that can be used for agriculture and forestry purposes.
