This article talks about Fisheries as classic tragedy of the commons example. It goes on to explain that since fish migrate to mate or lay eggs it is more difficult to set a private zone for certain fisheries. This often leads to some areas being over fished. The article then goes on to explain that their has been more effort made in order to privatize the commons, as experts have seen results of economic and ecological benefits from this practice.

The article I chose describes tragedy of the commons and describes how bacteria relates to that.

This article shows how the air in China is getting more polluted every year, and the population has only two choice: stay home or go around with a mask, hoping not to have any breathing problems. This connects with tragedy of the commons, since air is a common and people pollute it by using cars without thinking about the consequences. China is so populated, that the large use of cars is highly polluting the streets. In addition, there are industries that pollute and nothing is being done because air is a common.

This article discusses and reflects upon how the great BP oil spill in the Mexican Gulf relates to a typical tragedy of the commons situation. The writer states that the spill was due to overexploitation, which is quite an interesting and vital perspective when discussing the oil spill and its causes.

This me only be loosely related, but i found the article interesting. This could be looked at as a tragedy of the commons example, with Mali and Konna being viewed as the commons.

This article talks about the pollution of the water, and how most counties' water resources are getting more and more public since "one cannot own water". This is exactly what tragedy of the commons is. Since no one owns the water, people can do whatever they want there, without further (or a lot of) consequences. Also, it makes it harder for the government to regulate the resource in case of crisis.

This article talks a lot about the recent "fiscal cliff" that congress or some government branch put together to ensure that the two United States parties, the democrats and the republicans, tried to come to some sort of agreement on where cuts can be made to try and fix the deficit. What's interesting about this article, more than the content itself, is the site it links to which talks a lot about how individual cities are doing their part to try and fix up the country. The fact is, the US has gotten some very bad grades lately (whatever that means), so mayors and representatives are getting citizens to invest in projects that will cost a lot of money but will go a long way toward a better future. Fixing up public resources, like water ways and levies, is crucial to trying to build a better community, even if the effects are long term. This is probably the closest we'll see to a sustainable economy.

Just like overfishing in the sea, over-hunting on land is a tragedy of the commons. The tiger population in the world is endangered. However, it is now on the rebound as a result of the implementation of harsher legislation in some of the more prominent countries with tigers. This is an example of the ability of recovery.

The article describes the steps taken and possible solutions to the over-fishing in the oceans near Chile. Scientists work together with the fishers to find possible solutions. Also new fishing-laws have been set up after 17-years of dictatorship (now democracy).

As the article states: "The world's largest economies took a step toward common global guidelines for exchange-rate policies with a pledge Saturday to refrain from targeting their currency policies to gain a competitive trading advantage." This is well-involved in this week's topic, which is aggregate demand. Particularly, this article refers to its component, net exports (export revenue minus import expenditure, or simply X-M) and then its subsidiary component, changes in exchange rates. If a country's exchange rate becomes stronger, then this makes the country's exports more expensive to foreigners and vice versa. Manipulating with exchange rates can bring a certain country substantial trading advantage and this is what G-20 wants to overcome and allow free-trade market as it should be.

The article states that less than 2% of the African forests are commonly accessible.The deforestation rate is 4 times higher than any other in the world. The resources of the land are not allocated very well. Most of the forests were privatized by big intercontinetal companies, and were cut down by them. Common access resources are becoming rare, especially forests.

This article truly scares you with all the facts about food. It is a pity how mass food production turns out to be 50% inefficiently allocated and at the same time huge consumer of water for growing the crops. If all food produced was adequately allocated, there would be probably enough food for all people and therefore it would be almost completely accessible for general public. At the same time also water could be consumed more effectively instead of wasting it for pointless excess in food production which turns out to be industrial waste. Water - meaning the drinking water was never a Common, however nowadays it all appears this situation is getting only worse and taking into account its fruitless use, some measures should be taken designed with sustainability in mind.

Venezuela has joined Mercosur, six years after first applying to join the South American trading bloc. This article showcases features of economic integration, in this case customs union, which is a free trade area where members establish a common tariff and agree to other trade policies with non-member countries. Well, this article is particularly valuable also because it gives you that well-known sense of economic reality as a genuinely different economic world than that described in the economic theory. Countries cluster together for a mutual advantage, however, as opposed to comparative advantage concept and other highly cherished theoretical reasons, it always comes down to natural resources as vital sources of geopolitical influence, for instance oil, which is abundant in Venezuela. This can reasonably be inferred from the following quote: "Brazil said Mercosur was "also positioning itself as a global energy power in renewable and non-renewable resources". In the end, the disadvantages of economic integration are given, highlighting the fact that in economics there are perpetual advantages as well as disadvantages (influx of cheap agricultural products, little influence in decision-making processes). But then again, the disadvantages have to be explained within advantages in order to grasp the holistic situation (e.g. influx of cheap agricultural products forces Venezuelan farmers to cut down on their costs and improve on efficiency).
