We will build pollution-free hydroelectric energy generators using a submerged Columbia River pipeline, and deliver fresh water for agriculture and drinking. We will ease the problems of Global Warming, Rising Ocean Levels, Flooding, Drought, Pollution, Depletion of the Ozone Layer, the Blockage of Fish Migration by Dams, and Loss of Rain Forests, Grazing Land, and Agricultural Land through riverbottom pipelines in the world's major rivers.
