In "Principles of Conservation," how does the author develop the second principle of conservation, prevention of waste?

He states that the word conservation has three principles to it. One being that conservation stands for development; that these resources on Earth are here for the benefit of society today. He believes that we should be developing these resources and using them to the fullest extent for this generation. We should be recognizing that the present generation has the right to these resources to meet our demand, and then the remaining is for the next future generation.

The second principle of conservation that this article states is the prevention of waste and that our duty as humans is to have control of the Earth that we live on. We should be controlling the waste of these resources, like the waste of timber in a forest fire for example.

The third principle of conservation is that these developed and preserved resources should benefit many people and not just a few. They should be considered a common good.
