NEET BIOLOGY

Detailed explanation-1: -Over-harvesting means taking more from the land (or sea) than it can replace. It includes extreme farming, grazing, fishing, and using fresh water.

Detailed explanation-2: -Overharvesting, or overfishing in the case of fish and marine invertebrates, depletes some species to very low numbers and drives others to extinction. In practical terms, it reduces valuable living resources to such low levels that their exploitation is no longer sustainable.

Detailed explanation-3: -Overharvesting stems from several factors, including an exponential increase in the human population, expanding markets, increasing demand, and improved access and techniques for capture.

Detailed explanation-4: -Catching fish is not inherently bad for the ocean, except for when vessels catch fish faster than stocks can replenish, something called overfishing.

Detailed explanation-5: -What is overfishing? Overfishing means fish are being caught faster than they can reproduce, hindering their ability to maintain healthy population numbers. Overfishing is a global problem, and it’s causing fish populations to decline and harm to ocean ecosystems.
