Probably makes sense, but you'd have hard time to pull this one off given the state of modern-day press and other media. Suppose scientists calculate seawater contains, on average, N parts per million of Uranium and aim at inceasing it to just N+1 (assuming N >> 1). Armchair `ecologists' -- think Greenpeace -- would go thermonuclear on you -- and mass media would give those `ecologists' much more print space and air time than to the scientists. Public opinion would be skewed from the get-go.
