When the giant flightless birds called moa were overexploited to the point of extinction, [5] the giant Haast's eagle that preyed on them also became extinct. [6]The concern about overexploitation, while relatively recent in the annals of modern environmental awareness, traces back to ancient practices embedded in human history.
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]
While marine pollution can be obvious, as with the marine debris shown above, it is often the pollutants that cannot be seen that cause most harm.. Marine pollution occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there.
Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
With primary causes being warming ocean waters, ocean acidity, and pollution. [3] In 2008, a worldwide study estimated that 19% of the existing area of coral reefs had already been lost. [ 4 ] Only 46% of the world's reefs could be currently regarded as in good health [ 4 ] and about 60% of the world's reefs may be at risk due to destructive ...
Additionally, industrial processes often generate pollution and waste, further exacerbating environmental impacts and threatening ecosystems and biodiversity. industrialization has been associated with the commodification of natural resources, where resources are valued primarily for their economic potential rather than their intrinsic ...
President Luiz Inácio Lula da Silva sent his condolences to the families of the victims in a post to social media Monday, and said his government will support local authorities in dealing with ...
Environmental disasters have historically affected agriculture, wildlife biodiversity, the economy, and human health.The most common causes include pollution that seeps into groundwater or a body of water, emissions into the atmosphere, and depletion of natural resources, industrial activity, and agricultural practices.
