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]
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 ...
Some remain on the ocean's surface; microplastics account for 92% of plastic debris on the ocean's surface, according to a 2018 study. [83] And some sink to the ocean floor. Australia's national science agency CSIRO estimated that 14 million metric tons of microplastics are already on the ocean floor in 2020. [84]
Researchers found an increase in common dolphin sightings in the English Channel and Hebrides, and a decline in white-beaked dolphins in the Hebrides.
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 ...
The study focused on how the North Atlantic Oscillation influences subpolar North Atlantic Ocean temperatures. This new “ocean memory framework” accounted for short-term local effects ...
An oiled gannet seabird getting the oil washed off.. Most of the impact was on the marine species. Eight U.S. national parks were threatened [4] and more than 400 species that live in the Gulf islands and marshlands are at risk, including the endangered Kemp's ridley turtle, the green turtle, the loggerhead turtle, the hawksbill turtle, and the leatherback turtle.
The Italian study has weaknesses, but is likely to draw attention to the debate over the problem of plastic pollution. Most plastic waste is never recycled and breaks down into these particles.
