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.

This article talks about the decline in deforestation in Brazil of the Amazon. It states that the deforestation in brazil has decreased dramatically from its peak in 1995, at 30 000 square km per year to 4656 square km this year. Although this doesnt seem as alot of space..its actually the size of The New York state. This has all happend due to the rising awareness of the Government to preserve the Amazon. Althoigh enviromentalists are still not completelty happy because the Brazilian government recently signed an agreement in favor of the farmers cutting down trees to increase agriculture. The Brazilians government is planing to reduce deforestation to 3925 by 2015. this is a market failure because by cutting down trees it affects the oxygen levels in the atmosphere increasing the effects of global warming.
