Pollution from the Motiva refinery in Norco, Louisiana has been a major pollutant in the region since 2005, and it doesn't show signs of stopping. There have been 301 reported cases of accidents in 2011 and many more unreported. The firm may be only concerned with its marginal private costs and have no intention in even dealing with the marginal social costs caused by the negative externality. The government must intervene and cease this crime; the injustice towards its community, society and the environment.

I didn't heard about this case before. I find it ironic because USA with their great judiciary don't have methods to fight with companies like Motiva. We can ask ourselves who is worst a murderer who kills one person and is sentenced to death or a company who is killing hundreds of humans beings. The oil is very important in our live, we need it every day but we must ask as where is the limit? what is more important a human being or using a car? We have to eliminate negative externalities like pollution because if we don't do anything then we will destroy the world because we have infinite wants (this is the sad reality).

Scientists in Alberta have found evidence that oilsand operations have been sending toxins into the atmosphere for decades. Also, levels of toxins in Namur Lake have tripled since 1960. Critics have raised serious concern over the rising pollution in our atmosphere and lakes. This relates to our lesson for the week because the atmospher and lakes are common access resources. They are open to the common. These resources are becoming depleted because of the overuse of these resources.

It is a very interesting article because it is a very recent theme. In the last week I read that the soot is three times more polluting than the scientist though. It is a very good example of negative externality of production. The toxins in the atmosphere are negative externalities for third parties. The company will produce at q1 concerned in their own cost. The MSC is higher than the MPC and there is a welfare lost from Q1 to the equilibrium point. I think that commons must be protected and to achieve it the government must intervene to save the atmosphere and the lakes because it is our planet and we must save it.
