The water resource problem in the video is overfishing. Overfishing is a problem that occurs when fishermen catch fish at a rate faster than they can reproduce. I think overfishing originated when fishermen began using bigger and better fishing nets and techniques. Better fishing equipment resulted in overfishing‚ which is a major water resource problem. Depletion of the fish population is a problem that could be managed. Even though‚ it is difficult for the depleted stocks to return to sustainable

As our population is increasing we are facing many problems‚ one of the problem is overfishing. Overfishing is caused by the increasing demand (need) of fish. The more demand of fish there is the more fishers have to catch. The reason for this is because the more fish‚ fishers catch and sell‚ the more money they get. This is proven by Young People’s Trust for the Environment because they say‚ “It is human nature to try to make as much money as possible.” The more fish‚ that is caught the less fish

science Overfishing is a situation where one or more fish stocks are reduced below predefined levels of acceptance by fishing activities. More precise definitions are provided in biology and bioeconomics. Biological overfishing occurs when fishing mortality has reached a level where the stock biomass has negative marginal growth (slowing down biomass growth)‚ as indicated by the red area in the figure. Economic or bioeconomic overfishing in addition to the biological dynamics takes into consideration

commercially valuable species are overexploited‚ other species and habitat that share the same ecosystem are affected. According to many marine scientists and marine ecologists‚ unsustainable (overfishing) fishing is the greatest threat to the ocean ecosystems. For example‚ recent scientific studies suggest that overfishing of large shark species has had a ripple effect in the shark’s food chain‚ increasing the number of species that are sharks’ victims‚ such as rays. Rays are usual prey for large sharks

The Impact of Overfishing Overfishing has become an enormous problem all over the world. The impact of the increasing demand for fish and the advanced techniques made in the area of commercial fishing has caused some species of fish to be virtually extinct. In fact‚ some species like the giant bluefin tuna widely used by Japanese chefs and served in many restaurants‚ are now just few years away from extinction. Human demand for fish has increased enormously over the last several years‚ particularly

How does overfishing occur? What can we do to combat overfishing? There is a high demand for fish‚ and this along with increasingly more effective fishing techniques is causing overfishing. Some of the fishing methods that contributing to overfishing: Drift netting (between 2 boats) Longline fishing (up to 100km behind the boat) Radar/Sonar technology making it easier to find schools of fish No single country can be blamed for overfishing‚ but many countries

No fish‚ sharks‚ turtles or squid‚ no sea life‚ no life of beauty‚ just water‚ all because of our careless overfishing‚ draining the waters of it’s exuberant life.This is what the not so far out future generations might be left with‚if we don’t do something about it‚ and soon. Overfishing is a global catastrophe affecting anyone and everyone in one way or another. Overfishing is when fisheries take unsustainably large amounts of targeted and untargeted fish species at a rate that they can

1990s‚ the most of mitigation programs were solely focus on natural hazards (Roberts‚ p. 134). The maximum end of creating a mitigation directorate was to move the agency away from national security functions toward natural hazards that are more easily mitigated than prevented (Roberts‚ p. 134). James Lee Witt‚ oversaw FEMA reorganization and he as the director promoted the idea of mitigation at the local and state level throughout the 1990s. As a result‚ mitigation became associated with the policies

CHAPTER 7 HAZARD MITIGATION This chapter will explain what hazard mitigation is‚ and how it fits in with the other phases of emergency management. Next‚ the chapter will describe the most widely used mitigation strategies and the ways they are applied to the most common types of environmental hazards. The following section will describe the legal basis for hazard mitigation as it stands in the United States today. Problems in the adoption and implementation of mitigation policies will be described
