dams cause lots of problems: interruption of aquatic migration, habitat fragmentation, sedimentation, flooding (which completely covers entire villages), displacement of villagers (with no decent replacement living situation). More importantly, although the dams could potentially provide a lot of water to drought-stricken regions and electricity to cities, India lacks the infrastructure to make these benefits possible. |

romantic: Thoreau, Muir, Audubon. argued that nature is the sublime, has inherent beauty. scientific: demystified nature, broke it into pieces, tried to find out what was really in control. later: we want to preserve places with lots of scientific value so that we can use them for their utilitarian value in terms of things such as medicine an scientific discoveries. utilitarian: commodification of nature, it's something you can own, trade, and sell. it is only good for what you can get out of it. |
