STOP POLLUTING!
drinking polluted water can make you throw up (or it kills you) polluted water kills fish and other species polluted water releases greenhouse gases if it is continued over a long time, let's say a billion years, the oceans will melt, and the earth will become lethal for everyone the giant cloud of greenhouse gases now releases lightning, you see a red lava plume beneath the destroyed/polluted road, and the earth is now a dead planet.
