When there is an oil spill, it needs to be cleaned up for the sake of the environment and the creatures that lives in it. It order to have the clean up done as properly as possible, the area must be sealed off and only authorized people can enter it. For this reason, fishermen or any other people who want to be in the area for commercial purposes are not allowed to enter. Since the fishermen cannot enter the area, they cannot catch the sea creatures which results in the decline in supply of seafood. During the oil spill in the Gulf of Mexico, fishing was banned in the area as reported by Reuters, and some fishermen signed to help contain the spill.
The Exxon Valdez oil spill that happened in Alaska in 1989 as the result of an oil tanker’s collision with Prince William Sound’s Bligh Reef had adversely affected the economy of Cordova, a city in Alaska by damaging stocks of herring and salmon in the area. As you may have learnt in economics, when supply decreases, price increases. With the supply of seafood being reduced, the price of seafood increases. The increase in price is to control the amount of seafood being release to the public so that there will be enough seafood in the future. This is why you have to pay more for seafood whenever its supply is negatively affected. The greater the oil spill is, the wider the area it will cover, and the greater the effect it has on the supply of seafood. Although, the sea creatures itself may not be very much affected but getting them is impossible when the area is being sealed off for cleaning.
