Plastic pollution does not only affect animals that live solely in oceans. Seabirds are also greatly affected. In 2004, it was estimated that gulls in the North Sea had an average of thirty pieces of plastic in their stomachs. [206] Seabirds often mistake trash floating on the ocean's surface as prey.
Plastic pollution affects at least 700 marine species, including sea turtles, seals, seabirds, fish, whales, and dolphins. [51] Cetaceans have been sighted within the patch, which poses entanglement and ingestion risks to animals using the Great Pacific Garbage Patch as a migration corridor or core habitat. [52]
The North Atlantic garbage patch is a garbage patch of man-made marine debris found floating within the North Atlantic Gyre, originally documented in 1972. [1] A 22-year research study conducted by the Sea Education Association estimates the patch to be hundreds of kilometers across, with a density of more than 200,000 pieces of debris per ...
In 2018 approximately 513 million tonnes of plastics wind up in the oceans every year out of which the 83,1% is from the following 20 countries: China is the most mismanaged plastic waste polluter leaving in the sea the 27.7% of the world total, second Indonesia with the 10.1%, third Philippines with 5.9%, fourth Vietnam with 5.8%, fifth Sri ...
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.
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.
To dispose of animal waste and other pollutants, animal production farms often spray manure (often contaminated with potentially toxic bacteria) onto empty fields, called "spray-fields", via sprinkler systems. The toxins within these spray-fields oftentimes run into creeks, ponds, lakes, and other bodies of water, contaminating bodies of water.
Garbology is the study of modern refuse and trash as well as the use of trash cans, compactors and various types of trash can liners. It is a major source of information on the nature and changing patterns in modern refuse, and thereby, human society.
