LETTERS Our nation is becoming desperate to remove foreign oil as a major energy source, so I am active in advocating more energy from streamﬂow. Hydroelectricity is the Paciﬁc Northwest’s biggest potential natural resource contributor to cheap, renewable alternative energy. Certainly ﬁsh runs must be preserved, as should agriculture, but is dam removal the answer? With all the dams on the Klamath and Trinity Rivers, could not more water be released to improve the summer ﬁsh-migration runoff, impounding water during maximum snowmelt? Maybe more dams are needed to store water in deep basins in the winter months. Cold water from the bottom of reservoir or lake impoundments should be released for cooler summer ﬁsh runs. I am delighted that the interested parties are going to ﬁnd a solution. I hope they keep in mind that more cheap hydro energy is necessary if payments to foreign oil producers are going to be reduced. RAY O. SIMS Roseburg, Oregon You are correct in saying “The issues in play over the Klamath’s future are complex.” That is an understatement. Not all affected parties were invited to the conferences. Tonight in the local paper is an article about how the Siskiyou County Board of Supervisors opposes dam removal. This could turn uglier. Stay tuned. WILLIAM R. JANSON Montague, California Visions of Mars John Updike wrote about Mars with ecstatic enthusiasm: “In this tranquil desolation, the irruption of our live curiosity and systematic purpose feels heroic.” Our “heroic” efforts to study Mars and outer space seem to be misplaced, since the direct beneﬁciaries of this heroism are only two groups: the industrial establishment that produces the hardware for these explorations, and a privileged class of scientists. DARWIN TORRES CASTILLO Pereira, Colombia I look up at Mars and wonder whether we’ll ever get there. Space exploration would be an investment in our future and a beneﬁt to all humanity.
