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.
Plastic debris can absorb toxic chemicals from ocean pollution, potentially poisoning any creature that eats it. [118] Aside from toxic effects [119] when ingested some of these affect animal brain cells similarly to estradiol, causing hormone disruption in the affected wildlife. [120]
A garbage patch is a gyre of marine debris particles caused by the effects of ocean currents and increasing plastic pollution by human populations. These human-caused collections of plastic and other debris are responsible for ecosystem and environmental problems that affect marine life, contaminate oceans with toxic chemicals, and contribute ...
Plastics accounts for 80% of waste dispersed in the marine and coastal environment of the Mediterranean Sea. [24] Recent studies focus on the types of plastics found and primarily on the issue of microplastics, both at a global but also at a regional level, as in the case of the Mediterranean Sea, which was identified as a "target hotspot of the world" due to its amounts of microplastics ...
As the ocean warms, mixing between water layers decreases, resulting in less oxygen and nutrients being available for marine life. [49] Short term effects can be seen in acutely fatal circumstances, but other sublethal consequences can include impaired reproductive ability, reduced growth, and increase in diseased population. [50]
Sea dumping is a major contributor to the pollution of water in Lebanon. Sea dumping refers to the practice of disposing waste or debris into the ocean or along the coastline of a body of water. This practice has numerous negative effects on the health of the environment, marine life and humans in the area.
Ocean Conservancy is a non-profit environmental group that fights for the improvement and conservation of marine ecosystems and marine life. They work to find science-based solutions to protect the world's oceans from the global challenges that they face today. [7]
