Ocean overfishing is simply the taking of wildlife from the sea at rates too high for fished species to replace themselves. The earliest overfishing occurred in the early 1800s when humans, seeking blubber for lamp oil, decimated the whale population. Some fish that we eat, including Atlantic cod and herring and California's sardines, were also harvested to the brink of extinction by the mid-1900s. Highly disruptive to the food chain, these isolated, regional depletions became global and catastrophic by the late 20th century. When It Started Marine scientists know when widespread overfishing of the seas began. In the mid-20th century, international efforts to increase the availability and affordability of protein-rich foods led to concerted government efforts to increase fishing capacity. But by 1989, when about 90 million tons (metric tons) of catch were taken from the ocean, the industry had hit its high-water mark, and yields have declined or stagnated ever since. When It Will End

Japan Whaling Assoc. -Q&A- In Article VIII of the International Convention for the Regulation of Whaling (ICRW), the Contracting Parties have an unrestricted right to take whales for scientific research. Japan is a signatory to this Convention. When the commercial whaling moratorium was introduced in 1982, the main reason the anti-whaling nations gave for its introduction was the uncertainty surrounding the scientific data then available. In other words, they argued that safe management of whales was not possible because knowledge of the number of whales, age composition, sex ratio, and natural mortality rate was ambiguous. The research catch by Japan was launched to answer such questions and resolve the uncertainties.

Overfishing "There's enough on this planet for everyone's needs but not for everyone's greed" - Mahatma Gandhi For our children to have future income, food and pleasure we need healthy oceans and a healthy fishing industry. We need to create ocean sanctuaries to improve the state of our oceans and our fish populations. We need to vastly improve the way we fish, so it is not wasteful and damaging, but first we urgently need to stop taking fish faster than our oceans can replenish. It’s really simple housekeeping. But common sense is not working at the moment.

Why is overfishing a global concern? The problem of Overfishing We all love to eat fish, don’t we? It is the best source of protein and very healthy food in many ways. We also know where fish comes from—our oceans. Young People's Trust For the Environment It has been estimated by the United Nations Food and Agriculture Organisation that over 70% of the world’s fish populations are either fully exploited or depleted. When talking about overfishing we usually use the term fish 'stocks' - as if fish were a product on the supermarket shelves. It is this idea that has led us to many of our world's problems today; that of seeing the natural world as a commodity - as a resource from which humans can take forever. Overfishing is one of the most dramatic examples of the devastating effects of our modern society's outlook on nature, and proof that our world's resources are not limitless.

10 Things You Can Do to Save the Ocean 1. Mind Your Carbon Footprint and Reduce Energy Consumption Reduce the effects of climate change on the ocean by leaving the car at home when you can and being conscious of your energy use at home and work. A few things you can do to get started today: Switch to compact fluorescent light bulbs, take the stairs, and bundle up or use a fan to avoid oversetting your thermostat. What are the impacts of overfishing Impact of overfishing It is very easy to predict the most obvious impact of overfishing — no more fish for humans! And this is only a few decades from now, if we do not act quickly and decisively.

The Dirty Truth About Plastic BPA, in turn, is becoming this year’s poster child for all our doubts and fears about the safety of plastic. New research highlighting the possible dangers of BPA has received tremendous media coverage. In mice, at least, BPA exposure at crucial stages of development induces observable changes (such as breast or prostate abnormalities) that last a lifetime. The research may be confusing to a layperson, yet some consensus has been reached: Last November a panel sponsored by the National Institutes of Health (NIH) determined that there was at least “some concern” about BPA’s effect on the fetal and infant brain. Around the same time, the Centers for Disease Control reported that researchers there had found BPA—the United States produces 6 billion pounds of it yearly—in 93 percent of urine samples from 2,500 Americans aged 6 to 85. Children under age 12 had the highest concentrations.

What causes overfishing? How does overfishing happen? The causes of overfishing can be placed into these three categories: Overcapacity: All over the world, many fishing industries have huge vessels, equipment and technology that they can deploy deep into the oceans. They can stay on the oceans for weeks and months and even process the fish before they come back ashore. Experts believe that all the world’s equipment combined is enough to fish on 4 earth-like planets.
