"Having said all of that, I realize that I have not decided any of those tough problems you have to work with: making the decisions between whether you develop resources or conserve them. And I know that sometimes we can talk about conservation and development going along together. These are decisions that you will have to make, decisions that the Secretary will have to make, decisions on which he will have to advise me. But in the final analysis, I know that we are all working toward the same goal: to see to it that this great and rich land, more richly blessed when we look at it in terms of our natural resources than any land on earth--and we are fortunate to have it that way--but that this great and rich land will develop in the years ahead, will develop the resources that will enable us to be the best fed and the best clothed and the best housed people in the world, but that will also retain for the generations to come those great areas of beauty and also an environment, clean air, pure water, which will be one that our children will want to live in. And I can think of no more exciting responsibility than that. So much of that action is right here. We often hear that the action is in the cities and there is a lot of action there; and some would say today that the action is in the universities, and certainly there is a lot of action there."
