political chemistry of oil spills and why this is an incredibly important‚ long‚ oily‚ hot summer‚ and why we need to keep ourselves from getting distracted. But before I talk about the political chemistry‚ I actually need to talk about the chemistry of oil.

humans consume and produce energy. In the 1990s‚ it was estimated that‚ “the annual global input of petroleum would be between 1.7 and 8.8 million metric tons‚ the majority of which is derived from anthropogenic sources.” Meaning the estimated amount of oil that would be used every year to meet the energy demand.(Leahy and Colwell 1990) Since this prediction‚ the amount actually used each year has grown considerably. Due to this increased use‚ there have been an equal amount of environmental response from

History When people first started to get involved in environmental ethics‚ the choices were based on “how does it benefit humans”. Most ethical perspectives were anthropocentric‚ human interests at the expense of nonhuman things. Such as clear cutting‚ or burning because we as humans can benefit more from the wood or the land‚ than the animals can benefit from it. The value of nonhuman things would depend on what the human needed the nonhuman thing for. In the early 1970’s some members

Alexa Resnick What does the safety legislation implemented after the Exxon Valdez oil spill say about the government’s changing role in protecting against environmental hazards and how have the laws since then become stricter? One of the biggest take-aways from the Exxon Valdez oil spill was that prevention techniques and response capability were not effective enough. The large-scale shipment of oil on supertankers during the 1960s made a serious accident almost unavoidable. During the 1980s‚ safety
