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.

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.

The ocean is one example of a common access ground. It's not exactly owned by anyone. The ocean is being explored more and more everyday. One way is through fisheries. The rapid increase in demand for fishes has led to the sudden decline of the fish populations. Take Bluefin tuna as an example. The increase in demand for tuna sushi has led to a huge depletion worldwide for the past 15 years. This has also led to an increase in price as the populations are becoming more rare. A Bluefin tuna once sold for more than £1m at a Tokyo auction. It is said that most of the tuna caught are shipped to Japan for consumption. Since the ocean has international access, coming up with regulations need to be communicated among many countries. 48 member nations of International Commission for the Conservation of Atlantic came out and voted to maintain strict catch quotas. This relates to the tragedy of the common. Anyone can access the ocean and catch as much fishes as they like. They only take into account the money they can gain from catching more tunas. This shows a lack of consideration of the generation where some are only concerned about themselves. Without strict regulations, the population of tunas may become extinct in the near future.

It is a very interesting article because many people doesn´t know about the problem with the fish population. We are depleting all the oceans and we don´t think about the consequence of our acts. The problem is that we are really selfish because no one care about the future generation. We will leave them a completely depleted world (this idea is very present in the film Avatar) However it is very difficult to control the people from capturing too many or too small fishes or other animals. It is a tragedy of commons because it is the depletion of a shared resource by individuals, acting independently and rationally according to each one's self-interest, despite their understanding that depleting the common resource is contrary to the group's long-term best interests.

The coral reefs in Sweden is an important common resource where it provides habitat for many marine life and maintains biodiversity. However increased human activities such as trawling and eutrophication has caused the number of coral reef sites from 3 to 1 and the last remaining site is in bad condition. Coral reefs, once damaged causes many of the species of marine life to disappear and extremely difficult and time staking effort is required to restore. This is an example of "tragedy of commons" and adequate measures must be made to prevent further tragedy from happening.

This article talks about the decline in coral reefs due to a virus affecting their growth. This is a huge problem for the oceans because coral reefs support around and estimated 75% of all sea life and with out them, well we wouldnt have any fish to catch. So the survival of corals in our seas is absolutely essential.
