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. [3]
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 ...
Researchers found an increase in common dolphin sightings in the English Channel and Hebrides, and a decline in white-beaked dolphins in the Hebrides.
Ocean acidification may also have an effect of 'gender discrimination' as spawning female corals are significantly more susceptible to the negative effects of ocean acidification than spawning male coral [73] Bamboo coral is a deep water coral which produces growth rings similar to trees. The growth rings illustrate growth rate changes as deep ...
Invasive species are defined by the U.S. Department of Agriculture as non-native to the specific ecosystem, and whose presence is likely to harm the health of humans or the animals in said system. [139] Introductions of non-native species into new areas have brought about major and permanent changes to the environment over large areas.
The film examines human impacts on marine life and advocates for ending fish consumption. The film explores environmental issues affecting oceans, including plastic pollution, ghost nets and overfishing, [2] and argues that commercial fisheries are the main driver of marine ecosystem destruction.

Research shows that marine plastic pollution has impacts on marine ecosystems and economic activities at various levels, [53] [54] but further studies are currently being conducted to thoroughly investigate the size of such impacts in the Mediterranean area, [2] both on marine biota and on human health.
