One of the most important resources currently on this earth are the wild fish stocks in the ocean. Fish are used worldwide for food and other dietary supplements, such as cod liver oil and shark cartilage. For some people groups, their daily catch of fish is their primary source of food. In addition to this, there is a vast recreational and commercial value of fish.
Fish are a very important part of the marine ecosystem.
With no fish, this ecosystem would be unbalanced and would collapse. Without this valuable resource of fish, many industries as well as people would disappear. But the wild fish stocks are decreasing rapidly. Illegal fishing such as fishing in a protected area, fishing a protected fish species, or taking too many fish. Destroying fish breeding and growing habitats by misuse by swimmers and boaters and pollution, such as oil spills.
