Question
Read the following
The biosphere includes all living things and extends from genes on the molecular level to ecosystems on the macro level. Recall that ecosystems provide numerous essential ecosystem services—or functions on which humans rely-such as nutrient cycling, water filtration, and soil formation.
Human activities such as polluting, farming, and fishing can impair the ability of ecosystems to provide ecosystem services. Such activities can also contribute to habitat loss and change the distribution of plants and animals on the planet. Scientists have measured extraordinary decreases in biodiversity-the variety of organisms often associated with the health of an ecosystem-and increases in extinction rates.
Approximately 25 percent of mammals and 42 percent of amphibians are estimated to be in threat of extinction. As the biodiversity of an ecosystem decreases, it becomes less stable and less able to recover when disturbances, such as pollution or fire, occur.
The current rate at which species are becoming extinct has prompted some scientists to declare the current period as the Sixth Mass Extinction.
Commercial fishing has had a huge impact on the collapse of many species of fish.
For example, North Atlantic cod are found in bays and ocean water as far out as the continental shelf. They feed on small invertebrates, have few natural predators, and are prized seafood. Centuries of overfishing, development of more efficient fishing methods, warmer waters, and habitat destruction have led to the decline of cod populations. This decline in a top predator like cod, along with declines in other top predator fish populations, has complex, often negative impacts on ocean food webs.
By harvesting species of fish at a rate faster than they can naturally reproduce, overfishing poses a serious threat to marine life. Some contributing factors to the problem are giant factory ships, use of sonar to locate large schools of fish, illegal and unregulated fishing, and increased demand for fish. Declining fish populations have disproportionate effects on nations that are economically dependent on fishing.
Figured 15 shows Some commercial fishing methods catch or harm non-targeted fish and animals, called bycatch.
Figure 16 shows Regulation of fishing and the development of marine preserves can help restore and maintain fish populations.
A. Cod population, 1968-1972
B. Cod population, 2003-2008

Human activities are having a big impact on the ocean, especially through things like pollution and overfishing. For example, scientists say that "approximately 25 percent of mammals and 42 percent of amphibians are estimated to be in threat of extinction" because of our actions. Overfishing is a major problem; fish like North Atlantic cod have been heavily caught, which hurts the food chain in the ocean. When we catch fish faster than they can reproduce, it makes it harder for their populations to recover. We need to take better care of our oceans to help restore fish populations and protect marine life!
