                                                  Pros and Cons of Nuclear Power
Sergei Supinsky: This storage facility near the site of the Chernobyl Nuclear Power Plant currently houses nuclear waste. What's nuclear power's biggest advantage? It doesn't depend on fossil fuels and isn't affected by fluctuating oil and gas prices. Coal and natural gas power plants emit carbon dioxide into the atmosphere, which contributes to climate change. With nuclear power plants, CO2 emissions are minimal. According to the Nuclear Energy Institute, the power produced by the world's nuclear plants would normally produce 2 billion metric tons of CO2 per year if they depended on fossil fuels. In fact, a properly functioning nuclear power plant actually releases less radioactivity into the atmosphere than a coal-fired power plant. Plus, all this comes with a far lighter fuel requirement. Nuclear fission produces roughly a million times more energy per unit weight than fossil fuel alternatives. And then there are the negatives. Historically, mining and purifying uranium hasn't been a very clean process. Even transporting nuclear fuel to and from plants poses a contamination risk. And once the fuel is spent, you can't just throw it in the city dump. It's still radioactive and potentially deadly. On average, a nuclear power plant annually generates 20 metric tons of used nuclear fuel, classified as high-level radioactive waste. When you take into account every nuclear plant on Earth, the combined total climbs to roughly 2,000 metric tons a year. All of this waste emits radiation and heat, meaning that it will eventually corrode any container that holds it. It can also prove lethal to nearby life forms. As if this weren't bad enough, nuclear power plants produce a great deal of low-level radioactive waste in the form of radiated parts and equipment. Over time, spent nuclear fuel decays to safe radioactive levels, but this process takes tens of thousands of years. Even low-level radioactive waste requires centuries to reach acceptable levels. Currently, the nuclear industry lets waste cool for years before mixing it with glass and storing it in massive cooled, concrete structures. This waste has to be maintained, monitored and guarded to prevent the materials from falling into the wrong hands. All of these services and added materials cost money -- on top of the high costs required to build a plant. Disponível em: Acesso em: abr. 2011.

Texto A
Society has always used punishment to discourage would-be criminals from unlawful action. Since society has
the highest interest in preventing murder, it should use the strongest punishment available to deter murder, and
that is the death penalty. If murderers are sentenced to death and executed, potential murderers will think twice
before killing for fear of losing their own life.
The death penalty certainly "deters" the murderer who is executed. Strictly speaking, this is a form of
incapacitation, similar to the way a robber put in prison is prevented from robbing on the streets. Both as a
deterrent and as a form of permanent incapacitation, the death penalty helps to prevent future crime.

Texto B
Before I get into comedic related issues, a quick statement on the death penalty (due to some Facebook chatter
on my page). I am against the death penalty in all cases. The recent revelation in Texas that an innocent man
was executed for arson and capital murder in 2004 for allegedly setting fire to his home, which killed his two
young children should be huge news. Can you imagine the man’s anguish (he never pleaded guilty)? But I am
against it even when the person is actually guilty (yes even if DNA and videotape corroborate it). I think it is
barbaric. China, parts of the Middle East and the U.S. are the world’s executors. No one else I believe.
