Context: U.S. Bottled Water Sales Are Booming Again Despite Opposition Despite organized anti-bottled-water campaigns across the country and a noisy debate about bottled water's environmental impact, Americans are buying more bottled water than ever. Why do so many people seem to think they should have any input on what other American's choose to buy or do? If they want to buy bottled water, let them. If they want to eat fast food, let them. If they want to smoke pot, let them. -- Barackalypse People just get tired of paying for others' bad behavior. If many people eat excessive fast food, you pay higher insurance premiums. If many people frequently buy bottled water, your trash bills go up and landfills fill up quickly.www.zxxk.com It's about personal responsibility, which really should be a cornerstone of libertarianism. -- Bdbr So? This is the price you pay to live in a free society. You want to control the life of another just so you can save a few bucks? What would you say when someone do the same to you? -- Norman619 Defend selfish pricks all you like; I'm just glad there are still people who still believe personal responsibility is a good and decent thing. We make your life cheaper and less bothersome. -- Yoyo What a waste of money! It's fine when you're on the road and you need a cold drink, but people who buy cases of bottled water for home are completely crazy. -- Agmlauncher I wish we all can find a way to improve things and benefit from this. The environment needs a lot of help but businesses will always work on what people would need and demand. Is this part of the balance? Hope we can find better ways. -- Skipweis

Context: Nuclear fission is the splitting of the nucleus of a radioactive atom into two smaller nuclei. This type of reaction releases a great deal of energy from a very small amount of matter. Fission of a tiny pellet of radioactive uranium- 235, like the one pictured in the Figure 1.1, releases as much energy as burning 1,000 kilograms of coal! Q: What causes the nucleus of uranium-235 atom to fission? A: Another particle collides with it. The Figure 1.2 shows how nuclear fission of uranium-235 occurs. It begins when a uranium nucleus gains a neutron. This can happen naturally when a free neutron strikes it, or it can occur deliberately when a neutron is crashed into it in a nuclear power plant. In either case, the nucleus of uranium-235 becomes extremely unstable with the extra neutron. As a result, it splits into two smaller nuclei, krypton-92 and barium-141. The reaction also releases three neutrons and a great deal of energy. It can be represented by this nuclear equation: 235 U 92 141 + 1 neutron 92 36 Kr + 56 Ba + 3 neutrons + energy Note that the subscripts of the element symbols represent numbers of protons and the superscripts represent numbers of protons plus neutrons. The neutrons released when uranium-235 fissions may crash into other uranium nuclei and cause them to fission as well. This can start a nuclear chain reaction. You can see how this happens in the Figure 1.3. In a chain reaction, one fission reaction leads to others, which lead to others, and so on. A nuclear chain reaction is similar to a pile of wood burning. If you start one piece of wood burning, enough heat is produced by the burning wood to start the rest of the pile burning without any further help from you.

However, if a nuclear chain reaction is controlled, it produces energy much more slowly. This is what occurs in a nuclear power plant. The reaction is controlled by inserting rods of nonfissioning material into the fissioning material. You can see this in the Figure 1.4. The radiation from the controlled fission is used to heat water and turn it to steam. The steam is under pressure and causes a turbine to spin. The spinning turbine runs a generator, which produces electricity. In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution that harms the health of living things. The air pollution also causes acid rain and contributes to global warming. In addition, fossil fuels are nonrenewable resources, so if we keep using them, they will eventually run out. The main advantage of nuclear energy is that it doesnt release air pollution or cause the other environmental problems associated with the burning of fossil fuels. On the other other hand, radioactive elements are nonrenewable like fossil fuels and could eventually be used up. The main concern over the use of nuclear energy is the risk of radiation. Accidents at nuclear power plants can release harmful radiation that endangers people and other living things. Even without accidents, the used fuel that is left after nuclear fission reactions is still radioactive and very dangerous. It takes thousands of years for it to decay until it no longer releases harmful radiation. Therefore, used fuel must be stored securely to protect people and other living things.
