“Property is the Right of Increase” – Pierre-Joseph Proudhon

"If a man has the right to self-ownership, to the control of his life, then in the real world he must also have the right to sustain his life by grappling with and transforming resources; he must be able to own the ground and the resources on which he stands and which he must use. In short, to sustain his human right." Murray Rothbard

"Pollution and overuse of resources stem directly from the failure of government to defend private property. If property rights were to be defended adequately, we would find that here, as in other areas of our economy and society, private enterprise and modern technology would come not as a curse to mankind but as its salvation." Murray Rothbard
