“We have become great because of the lavish use of our resources and we have just reason to be proud of our growth. But the time has come to inquire seriously what will happen when our forests are gone, when the coal, the iron, the oil, and the gas are exhausted, when the soils shall have still further impoverished and washed into the streams, polluting the rivers, denuding the fields, and obstructing navigation…the minerals do not renew themselves. Therefore in dealing with the coal, the oil, the iron, metals generally, all that we can do is try to see that they are wisely used. The exhaustion is certain to come in time.”—Theodore Roosevelt
