Liberty requires opportunity to make a living--a living decent according to the standard of the time, a living which gives a man not only enough to live by, but something to live for.
Franklin D. Roosevelt[M]y conception of liberty does not permit an individual citizen or a group of citizens to commit acts of depredation against nature in such a way as to harm their neighbors and especially to harm the future generations of Americans. If many years ago we had had the necessary knowledge, and especially the necessary willingness on the part of the Federal Government, we would have saved a sum, a sum of money which has cost the taxpayers of America two billion dollars.
