The definition of over fishing is to deplete the number of fish in a body of water by too much fishing. Overfishing is very harmful to the ecosystem, taking a species close to extinction or completely extinct. As a species gets close to extinction it can be very hard to restore them back to sustainability. Even closing the fishing game for that species is not enough for a species to comeback from overfishing. Both recreational and commercial fishing have a huge impact on overfishing, by keeping under sized fish and other aquatic life.
The cod fishing industry employed most of the population and also influenced other industries in the region to grown alongside such as the shipbuilding industry and the export of timber to European and Caribbean countries. When the government banned cod fishing in 1992, many people lost their jobs. Hence, Newfoundland’s fishing industry diversified and shellfish; the previously ignored group of fish now became the most valuable. After the cod collapse, Newfoundland’s major source of income were queen crabs and shrimp. However, many people were still left unemployed.
I grew up in Westfield, with you as my state legislative representative. In the course we learned about one of the biggest, arguably the biggest, threat facing the world’s oceans today: overfishing. Overfishing is when fish are being taken out of the ocean faster than they can reproduce. This is occurring all over the world, including right off our very own shores. This has a myriad of impact in the marine ecosystem and well beyond.
Without sharks, there would be an increase in several other carnivores, leading to a vast decrease in the amount of shellfish and other herbivores in the sea, which can be detrimental to local fisheries. Fishermen hunt sharks in order to sell their meat for money, however, those sharks are crucial to the survival of other desirable marine life such as shellfish, which fishermen also fish. So these fishermen are putting their own businesses at risk because once sharks are gone, everything is
Although there are many groups of people who depend on oceans for sustainable livelihoods, they are the most vulnerable because they become so reliant on natural resources and are harming themselves without even knowing it. Oceans are increasingly threatened, degraded or destroyed by human activities, as this causes the oceans to reduce their ability to provide crucial ecosystem services. Important threats that
The act of hunting whales has been around since the beginning of human history. However, overexploitation throughout the last centuries has severely depleted these species. Yet still, thousands of whales are killed each year for profit. Mankind’s avaricious nature for more money has driven these creatures to their demise. Despite that, an increasing number of people worldwide are against commercial whaling.
This initiative should be considered by all governments as soon as possible in the hopes of saving the endangered sharks. Otherwise, without sharks, the ocean biological system will be unbalanced, thus affecting the entire food chain. If the populations of planktons or other small creatures increase, consequences will follow. The control and management of the oceans will be tougher if the population of small fishes were to greatly increase. The outbreak of diseases in the ocean will be induced and this may spread to rivers and lakes which will ultimately affect us since our drinking water would become
In the eyes of society and the public, sharks are viewed as ruthless killers Millions upon millions are killed every year, and fear is a major contributor. The reality is that sharks are very complex creatures, and should be treated as such. They are an intricate part of the ocean’s ecosystem and the ecosystem would be completely thrown off without them. We need to realize that these creatures are invaluable, and that we must conserve these animals. If we do not realize this reality, we could lose sharks forever.
Overfishing is defined as human take out more fish from ocean than the fish can naturally replenish. It is caused by several factors. First and foremost, overpopulation increases global fish demand for food. Moreover, with higher quality of life and due to the traditional culture such as shark fin soup in China, people are more capable paying for fish and hence expensive fish species are overexploited by fishers to maximize their profit. Second, to cope with increasing demand, advances in fishing gear technology to capture fish in massive scale within a short period of time within the last 50 years that are also environmentally damaging.
As they usually hunt old, weak or sick prey, they help to keep the prey population in good condition, healthy and strong, enabling these more naturally fit animals to reproduce and pass on their genes. The effects of removing sharks from ocean ecosystems, although complex and rather unpredictable, are very likely to be ecologically and economically damaging. Here are some reason why killing sharks is very bad: 1)Sharks are being fished at a rate faster than they can recover. Due to overexploitation and lack of proper management, many shark species are under considerable risk of unrecoverable decline with some species having declined to near extinction in recent years. According to reports, sharks are being killed at an alarming rate of up to 273 million worldwide per year.
