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.

National Geographic 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 biology Only 29 percent of the world surface is land. The rest is ocean, home to the marine lifeforms. The oceans average nearly four kilometres in depth and are fringed with coastlines that run for 360,000 kilometres.[1][2] A large proportion of all life on Earth exists in the ocean. Exactly how large the proportion is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world[3] covering about 71% of the Earth's surface.
