Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons, estuaries and inland seas. By volume, oceans provide about 90% of the living space on Earth, and served as the cradle of life and vital biotic sanctuaries throughout Earth's geological history. [1]
Coverage[]
Marine life were featured in the documentary.
In 150 years after people, marine life welcomed the disappearance of mankind as the oceans are teeming with life once again. Steve Palumbi explains that humans have historically treated the oceans in 2 strange ways at the same time, being fishing and sewage, and the ability to damage the ocean has grown overtime. Without people to fish and polluting the sea, marine life saw an astonishing recovery from the cleared path, with an historic example happened during World War II when the populations of fish skyrocketed in the North Atlantic after Allied fishing trawlers intentionally avoided it.
Steve Palumbi explains the biology of the sunfish, which could produce millions of offspring in a year.
Steve Palumbi explains the basic biology of marine life and its advantage like the sunfish which can produce millions of offspring in a year, more than an equivalent-sized terrestrial animal like a cow. He continues that because of the prodigious potential to reproduce, the oceans could come back pretty quickly.
The documentary also provide another example from a research that shows that in the 18th century, the oceans were capable of sustaining massive amounts of life before the havoc caused by humans. Steve Palumbi states that many whales stink up the air, many tunas froth the ocean, and so many turtles that one could walk across the sea on their back. He then concludes if people disappears, its the kind of ocean he stated could be.
The recovery of the population of marine life has also allowed the surviving seagulls to took advantage of it.
