    Oceans are one of the Commons, and as any other commons, it becomes overconsumed. Fishers all around the world keep devastating populations of the fish. To prevent overfishing, pollution and other human impacts, leading international marine scientists are proposing radical changes in the governance of the world's oceans. They carried an experiment in Chilie, and based on it, scientists state that they would be able to help to reverse "the tragedy of the commons". Problems in Chilie made people be open to new arrangements, scientists and fishers began working together to improve the situation with fish. By working together for some years, scientists became able to reveal about fish stocks and and the surrounding marine ecosystem. The new laws gave exclusive ocean territories to local 'artisanal' fishers, and excluded the big industrial fishing fleets, which had their own exclusive fishing zone. Scientists and small fishers then worked together to understand and rebuild the shattered fish stocks in their zone, leading to a shared vision and voluntary agreements on how to manage them.

    This article talks about an experiment made in Chile. The use given to our oceans are no good, the article encourages huge changes in the governance of world's ocean to save them from pollution, over-fishing and other impacts made by the humans. All of these factors affect the marine ecosystem in a drastic way, now the levels of fish are decreasing as it says in the article "There was a general recognition that Chile's fish stocks were in trouble," says Professor Carl Folke. This has led to some fisheries to collapse leading the Chilean government for being responsible to take actions.This serves as an example of what's happening in the world today and for facin this problem he suggests that "You need a shared recognition that something has to be done, you need a good understanding of the marine ecosystem and how to regenerate it, you need a strong rapport between scientists and fishers, and you need a political moment when sweeping changes can be brought in." This problem needs to be faced responsibly otherwise there will be almost no fish stocks in the future, treating our commons well is important for us humans as this affects goods that are importand for living.

    Leading international marine scientists are proposing radical changes in the governance of the world's oceans to save them from overfishing, pollution and other human impacts. "Marine ecosystems are in decline around the world. New transformational changes in governance are urgently required to cope with overfishing, pollution, global changes, and other drivers of degradation. Fishers and scientists had been working together on the problem for some years, trialling new co-operative models for fishery management, based on that science can reveal about the state of the fish stock and the surrounding marine ecosystem." The result is a national system of marine tenure that allocates user rights and responsibilities to collectives of fishers. The research indicates the key to managing fisheries depend on creating agreements that are both voluntary and flexible enough to cope with changes in the ocean environment, leading to fisheries that are both ecologically and socially sustainable.

    I find this article particularl interesting because due to a political change in Chile, it has now effected the common resource tradegy of the Oceans. It has reduced the over fishing in Chile, which has let the fish start to regenerate. The research has found out that the key to managing the fisheries depends on making decisions flexible enough to cope with the changes that the ocean goes through.

    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.
