26. • Volunteer #1 • We talk about consuming, or using up material resources, but actually we don't consume any matter. We only borrow some of the earth's resources for a while, taking them from the earth, carrying them to another part of the globe, processing them, using them, and then discarding, reusing, or recycling them. Copyright © 2010 Ryan P. Murphy

31. • Volunteer #2 • In the process of using matter we may change it to another form, but in every case we neither create nor destroy any measurable amount of matter. This results from the law of conservation of matter: In any physical or chemical change, matter is neither created nor destroyed but merely changed from one form to another. Copyright © 2010 Ryan P. Murphy

36. ―I’m shy but I’ll give speaking a shot.‖

41. • Volunteer #4 • How does this affect environmental science ? Although we can certainly make the environment cleaner, the law of conservation of matter says we will always be faced with pollution of some sort. This means that we must trade-off one form of pollution for another. Copyright © 2010 Ryan P. Murphy

47. • Volunteer #5 • This trade-off involves making controversial scientific, political, economic, and ethical judgments about what is a dangerous pollution level, and to what degree a pollutant must be controlled, and what amount of money we are willing to pay to reduce the amount of a pollutant to a harmless level. Copyright © 2010 Ryan P. Murphy

53. • Volunteer #1 Again. • The "throwaway" society found in most industrial countries is based on using more and more of the earth's matter and energy resources at a faster and faster rate. The earth receives a constant flow of energy from the sun, but for all practical purposes little matter enters or leaves the earth. Copyright © 2010 Ryan P. Murphy

56. • Even with such a technological advance, the second energy law tells us that as we use more and more energy to transform matter into products and then recycle these products, the disorder in the environment will increase. Copyright © 2010 Ryan P. Murphy

57. • Even with such a technological advance, the second energy law tells us that as we use more and more energy to transform matter into products and then recycle these products, the disorder in the environment will increase. Thus the second energy law tells us that the more we try to order, or "conquer" the earth, the greater the disorder we put into the environment. Copyright © 2010 Ryan P. Murphy

58. • We will always attempt to order the environment to some extent for our benefit, but the second energy law helps us understand that we should do so with ecological wisdom, care, and restraint. Copyright © 2010 Ryan P. Murphy
