Overexploitation is one of the main threats to global biodiversity. [3] Other threats include pollution, introduced and invasive species, habitat fragmentation, habitat destruction, [3] uncontrolled hybridization, [37] climate change, [38] ocean acidification [39] and the driver behind many of these, human overpopulation. [40]
Greenpeace has found high levels of biodiversity in an area targeted for deep-sea mining, as concerns grow over the impact on ocean wildlife. The campaign group is surveying whales and dolphins on ...
Marine plastic pollution is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean.
Marine ecosystems are characterized by the biological community of organisms that they are associated with and their physical environment. Classes of organisms found in marine ecosystems include brown algae, dinoflagellates, corals, cephalopods, echinoderms, and sharks. Marine ecosystems are important sources of ecosystem services and food and ...
Climate change and invasive species. Buffelgrass (Cenchrus ciliaris) is an invasive species throughout the world that is pushing out native species. [1] Climate change and invasive species refers to the process of the environmental destabilization caused by climate change. This environmental change facilitates the spread of invasive species ...
The effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5][6] Habitats may change due to climate change. This can cause non-native plants and pests to impact native vegetation diversity. [7] Therefore, the native vegetation may become more vulnerable to damage.
Climate change is already now altering biomes, adversely affecting terrestrial and marine ecosystems. [2][3] Climate change represents long-term changes in temperature and average weather patterns. [4][5] This leads to a substantial increase in both the frequency and the intensity of extreme weather events. [6]
Marine life. Marine conservation, also known as ocean conservation, is the protection and preservation of ecosystems in oceans and seas through planned management in order to prevent the over-exploitation of these marine resources. Marine conservation is informed by the study of marine plants and animal resources and ecosystem functions and is ...
