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.
This decreased health of coral reefs, particularly the Great Barrier Reef, can result in reduced biodiversity. Organisms can become stressed due to ocean acidification and the disappearance of healthy coral reefs, such as the Great Barrier Reef, is a loss of habitat for several taxa. Ocean acidification makes it harder for organisms to ...
Biodiversity loss has bad effects on the functioning of ecosystems. This in turn affects humans, [ 45 ] because affected ecosystems can no longer provide the same quality of ecosystem services , such as crop pollination , cleaning air and water, decomposing waste, and providing forest products as well as areas for recreation and tourism .
A campaign group is surveying whales and dolphins in Norway’s waters as the country’s government pushes ahead with plans for deep-sea mining.
Furthermore, the ocean's function as a carbon dioxide sink, alterations in the atmosphere, ultraviolet light, ocean acidification, viral infections, the repercussions of dust storms transporting agents to distant reefs, pollutants, and algal blooms represent some of the factors exerting influence on coral reefs.
The collapse of Hovsgol's ecosystem during the LGM brought forth a new ecosystem, with limited biodiversity in species and low levels of endemism, in Hovsgol during the Holocene. That research also shows how ecosystem collapse during LGM in Lake Hovsgol led to higher levels of diversity and higher levels of endemism as a byproduct of subsequent ...
The oceans are not just a marine habitat. They are also a workplace, a highway, a prison, a grocery store, a trash can, a cemetery — and much more. Why we need to think about the oceans differently
In the ocean, they estimated that in the range between those "low" and "high" global warming scenarios, ocean net primary production would decline by 3% to 10% by the end of the century, while fish biomass would decline by 3% to 25%. Finally, even the lower warming levels of 1.5–2 °C (2.7–3.6 °F) would "profoundly" reduce geographical ...
