Chapter 18: Environmental Hazards and Human Health
3. This article deals with a regional issue.
4. The Gulf oil spill was extremely drastic and everyone wondered what would happen in the Gulf. Methane is one of the main components in the oil that was spilled into the Gulf. After only 4 months practically all the methane that was in the five million barrels of oil has been removed by a certain bacteria. However, just because the methane is gone does not mean the oil its self is gone. The oil is still found in the gulf in nearly everywhere in the deep water. Most of the ingredients of the oil haven't completely degraded. This discover of no more methane is very good not only for the Gulf but also the atmosphere. This is because the warming of ocean temperatures are thought to make parts of the ocean's geology less stable. This could trigger a huge release of methane gas into the ocean and potentially the atmosphere, which would contribute to global warming.
5. I think it is great that the methane has mostly completely gone by a natural source rather than us having to do something to remove the methane which could harm other things in the environment. This is also good because methane is a huge contributer to global warming and if we can cut down that amount of methane it can do the atmosphere a ton of good. It would be great if a natural source was able to remove the rest of the gas from the Gulf so it does not do any more damage.
