People will destroy Earth's biosphere

James Oberg : scientist, space journalist, historian
"The human population off Earth will exceed that on Earth well before the middle of the millennium, and that is NOT a null case" (one stranded astronaut watches a war-sterilized earth) but a robust, expansionist result. Technological solutions will be implemented to biosphere disasters ranging from environmental pollution, to hurricanes, to earthquakes, outwards to warding off falling space rocks, solar flares, and even interstellar supernova radiation."
