Document Summary
How we effect the environment and vice versa. It"s hard to be well in an un-well world. Organisms sharing a physical and chemical environment. Interrelationship between land, air, water, wildlife, human beings and activities. Carbon dioxide, methane, nitrous oxide, ozone, and water vapour. Co2 is important for insulation, it lets some radiation from sun into our atmosphere and keeps it there. Burning coal, oil and lumber release co2 into atmosphere. Instead of thing layer there"s a thick blanket. 32% more co2, than at beginning of era. Deaths (i. e. heat waves and vulnerable population) 12000lb of scrap aluminum used to buy bicycles for physical resources staff and campus police. Recover (use remaining waste to generate heat and power) Nature knows best (for every organic compound, there"s an enzyme to break it down) No such thing as a free lunch (all new technology makes us throw out the old)
