Tragedy of the Commons: Overfishing the World’s Oceans

Introduction Economic activity has been closely related to the environment since the concept of human trade was first discovered. In terms of economics, the environment itself becomes increasingly "scarce resource 1". As economics relates to managing these scarce resources, it will be a useful tool when considering some of the environmental problems facing our planet. One of the main problems facing today's environment is the overworking of the world's oceans, which is causing endangered species and consuming some species.

When access to marine resources is open, what is known as "the tragedy of commons" still exists. If the landline phone is not clearly marked, rules and regulations will be lost in the free ocean market, causing overfishing and depletion of fish species. In order to solve this problem, individual property rights are very necessary. In the field where the theory was verified, the results show less damage to fish stocks and less resources for harvesting (Grafton, Squires and Fox 2000).

Our sea has received tremendous pressure. We pour plastics and toxic chemicals into the sea, poison our own food, waste fish, catch it unsustainably, and 90% of the world's fish resources are completely caught and overfished . We have lost 50% of the world's coral reefs; in one generation, the world has lost more than a third of its marine species. Biodiversity - A network of complex life consisting of millions of species, plants, bacteria, fungi - supports the Earth system we consider natural. Water we drink, it maintains the ecosystem necessary for society to prosper and ensures access to necessary raw materials, goods and services. The unprecedented loss of biodiversity that we see today is a threat to the survival of human life and economic development. If the biodiversity index is considered to resemble the stock market, our planet will fall into a spectacular collapse.

The current major problem is overfishing. To overfish in the ocean means to catch fish at a high rate from the ocean, fish resources can not be fully recovered to dry. Since the ocean occupies more than 70% of the earth, the overall health of marine organisms and marine organisms is important for maintaining lives elsewhere on the planet, but overfishing is limited by oceans and onshore residents It had a big impact on the future. "When the catch amount exceeds the number of individuals, overfishing occurs and it can be replaced with natural breeding.It seems that collecting as many fish as possible is a useful way, but the possibility that overfishing can have serious consequences There is a balance between the social and economic well-being of the coastal community that is dependent on the lifestyle of the fish, and it affects it.
