Skin and eye irritation and lung and liver problems from oil deposits and byproducts. Reproductive system failure from exposure to poisonous industrial and agricultural chemicals.
When did marine pollution start?
Ocean pollution became increasingly apparent in the late 1960s, with researchers conducting some of the first intensive studies on plastic litter. Scientists noted occurrences of Laysan Albatrosses ingesting plastic items and northern fur seals becoming entangled in netting.

What are pollutants and how do they affect marine ecosystems?
Pollutants recognised as endocrine disruptors and teratogens, which impact the ability of marine species to reproduce or reduce offspring survival rates, present a growing concern (IPSO, 2019). Personal care products in particular contain cryptic chemicals that have a significant impact on human and ocean health (Dinardo and Downs, 2018).
