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.
With primary causes being warming ocean waters, ocean acidity, and pollution. [148] In 2008, a worldwide study estimated that 19% of the existing area of coral reefs had already been lost. [ 149 ] Only 46% of the world's reefs could be currently regarded as in good health [ 149 ] and about 60% of the world's reefs may be at risk due to ...
When oil spills occur, the affects can be felt in an area for decades and can cause massive damage to the aquatic life. For aquatic plant life an oil spill could affect how light, and oxygen is available for photosynthesis. [100] Coral Reef Community. Two other examples of the many ways oil harms wildlife are in the form of oil toxicity and ...
Living costs are a big overpopulation problem.
Freshwater species are beginning to decline at twice the rate of species that live on land or in the ocean. This rapid loss has already placed 27% of 29,500 species dependent on fresh water on the IUCN Red List. [100] Global populations of freshwater fish are collapsing due to water pollution and overfishing. Migratory fish populations have ...
Environmental justice is a social movement that addresses injustice that occurs when poor or marginalized communities are harmed by hazardous waste, resource extraction, and other land uses from which they do not benefit. [53] [54] The movement has generated hundreds of studies showing that exposure to environmental harm is inequitably ...
In the absence of predators, animal species are bound by the resources they can find in their environment, but this does not necessarily control overpopulation. In fact, an abundant supply of resources can produce a population boom that ends up with more individuals than the environment can support. In this case, starvation, thirst, and ...
