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]
Marine conservation is informed by the study of marine plants and animal resources and ecosystem functions and is driven by response to the manifested negative effects seen in the environment such as species loss, habitat degradation and changes in ecosystem functions [1] and focuses on limiting human-caused damage to marine ecosystems ...
Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean. Plastic pollution is harmful to marine life. Another concern is the runoff of nutrients (nitrogen and phosphorus) from intensive agriculture, and the disposal of untreated or partially treated sewage to rivers and subsequently oceans.
Human activities have a strong and detrimental influence on marine biodiversity. The main drivers of marine species extinction are habitat loss, pollution, invasive species , and overexploitation. [ 105 ] [ 106 ] Greater pressure is placed on marine ecosystems near coastal areas because of the human settlements in those areas.
Human-induced climate change "continues to warm the oceans which provide the memory of past accumulated effects". [61] The result is a higher ocean heat content and higher sea surface temperatures. In turn, this "invigorates tropical cyclones to make them more intense, bigger, longer lasting and greatly increases their flooding rains". [ 61 ]
While satellites and offshore buoys can inform scientists about marine heat waves, the effects on ocean species are less understood. Skip to main content. Sign in. Mail. 24/7 Help ...
Additionally, newer and better detection methods are needed for microplastics [41] and they must be installed at waste water treatment facilities [42] to prevent these particles from entering the marine environment and causing damage to marine life, especially coral reefs. Many people are realizing the problem of plastic pollution and other ...
A new study suggests that the human lifespan might be reaching its biological limit, and any increased advancements will likely come from studying aging rather than eliminating disease.
