Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
This plastic pollution harms an estimated 100,000 sea turtles and marine mammals and 1,000,000 sea creatures each year. [158] Larger plastics (called "macroplastics") such as plastic shopping bags can clog the digestive tracts of larger animals when consumed by them [ 13 ] and can cause starvation through restricting the movement of food, or by ...
Loggerhead sea turtle escapes from fishing net through a turtle excluder device (TED) Threats to sea turtles are numerous and have caused many sea turtle species to be endangered. Of the seven extant species of sea turtles, six in the family Cheloniidae and one in the family Dermochelyidae, all are listed on the IUCN Red List of Endangered ...
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 ...
He claims that even though mammals (such as humans) can have relatively long lifespans, we still operate under dinosaur-era restraints. Mammals may struggle to attain long life thanks to dinosaurs.
Mass extinctions are characterized by the loss of at least 75% of species within a geologically short period of time (i.e., less than 2 million years). [18] [51] The Holocene extinction is also known as the "sixth extinction", as it is possibly the sixth mass extinction event, after the Ordovician–Silurian extinction events, the Late Devonian extinction, the Permian–Triassic extinction ...
Today, people often resort to canned food when better options are lacking. Thousands of years ago, early humans may have turned to turtles, a new discovery reveals.
Or, more precisely, a universe-wide change in gravity helped kill the dinosaurs, by yanking a giant space rock out of its usual place on the edge of our solar system and hurtling it toward a ...
