Moving forward, encouraging recycling and reuse can minimize plastic pollution. Light pollution penetrates under the water, creating a vastly different world for fish living in shallow reefs near urban environments. Many of these pollutants sink to the ocean's depths or float far distances from their original source, where they are consumed by small marine organisms and introduced into the global food chain.

There can be several causes of ocean pollution, but the leading causes include sewage, toxic chemicals from industries, nuclear waste, thermal pollution, plasti… Excess nutrients entering a body of water, either through natural or human activities, can also result in hypoxia or dead zones. Toothed whales use echolocation—emitting sounds that reflect off surfaces—to help them “see” in the ocean. This type of pollution occurs when human activities, notably the use of fertilizer on farms, lead to the runoff of chemicals into waterways that ultimately flow into the ocean. Many of the marine species that live in these areas either die or, if they are mobile (such as fish), leave the area. Photograph by Ed Kashi, Nat Geo Image Collection.

Air quality measurements, collected by research associate Douglas Martins, characterized the pollution coming from terrestrial air masses. Over 50 years later, the tire reef still sits on the bottom of the lagoon. These excess nutrients trigger massive blooms of algae that rob the water of oxygen, leaving dead zones where few marine organisms can live. Ocean water covers more than 70 percent of the Earth, and only in recent decades have we begun to understand how humans impact this watery habitat. The research undertaken thus far extends beyond the effects of pollution on resource population size to disease effects in fish and humans, effects on aquaculture, and effects on productive systems of the oceans. Plastic waste is the most visible component of ocean pollution. Dirt can also spill into waterways from top soil or silt from fields or construction sites, causing endangerment to fish and wildlife habitats.

Nonpoint source pollution can make river and ocean water unsafe for humans and wildlife. For many marine mammals, like whales and dolphins, low visibility and large distances make non-visual underwater communication critical. Discharge from faulty or damaged factories or water treatment systems is also considered point source pollution. Before 1972, humans around the word spewed trash, sewage sludge, and chemical, industrial, and radioactive wastes into the ocean with impunity.

Pollution that comes from a single source, like an oil or chemical spill, is known as point source pollution. Plastic bags resemble jellyfish, a common food for sea turtles, while some seabirds eat plastic because it releases a chemical that makes it smell like its natural food. Pollution is not always visible. The oceans are losing mussel mass. All marine debris comes from people with a majority of it originating on land and entering the ocean and Great Lakes through littering, poor waste management practices, storm water discharge, and extreme natural events such as tsunamis and hurricanes.
