make sense to destroy the Arctic Refuge for oil that won't lower prices and

much easier to get the same amount of energy through common-sense conservation

exploration and exploratory drilling would radiate across the entire coastal

identified saltcedar as one of the most harmful invasive species in the United
States, because the plant's long roots tap into underground aquifers.
The ISFS uses observations and science data products from NASA's Terra ,
Aqua and Earth Observing-1 satellites and the USGS-operated Landsat
satellites, together with field data from government and non-government
contributors.
