An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity, and is a form of pollution. The term is usually applied to marine oil spills, where oil is released into the ocean or coastal waters , but spills may also occur on land.
The oil slick as seen from space by NASA's Terra satellite on 24 May 2010. The 2010 Deepwater Horizon oil spill in the Gulf of Mexico has been described as the worst environmental disaster in the United States, releasing about 4.9 million barrels (210 million US gal; 780,000 m 3) of crude oil making it the largest marine oil spill in history.
People can be exposed to the chemicals in oil by breathing them, swallowing, or touching them. Previous studies show consistent evidence of acute toxic effects, mainly neurological, ocular (eye), and respiratory, of those living in exposed communities and among clean-up workers. [1]
Seed oils are not only the healthier option for people—but potentially for the planet as well, says Kersten of sustainability issues surrounding animal-based fats.
Oil Impacts on Coral Reef Communities. Oil pollution is hazardous to living marine habitats due to its toxic constituents. Oil spills occur due to natural seepage and during activities such as transportation and handling. These spills harm the marine and coastal wildlife.
A 2020 study reports that by 2050 global warming could be spreading in the deep ocean seven times faster than it is now, even if emissions of greenhouse gases are cut. Warming in mesopelagic and deeper layers could have major consequences for the deep ocean food web, since ocean species will need to move to stay at survival temperatures. [69] [70]
Seed oils also get a bad rep because of their level of processing. It's more difficult to get oil out of a seed than it is, say, an olive, so seeds undergo a more intense oil extraction process.
For example, "green water" use is evapotranspirational use of soil water that has been provided directly by precipitation; and "green water" has been estimated to account for 94% of global beef cattle production's "water footprint", [90] and on rangeland, as much as 99.5% of the water use associated with beef production is "green water".
