The IPCC (2019) says marine organisms are being affected globally by ocean warming with direct impacts on human communities, fisheries, and food production. [67] It is likely there will be a 15% decrease in the number of marine animals and a decrease of 21% to 24% in fisheries catches by the end of the 21st century because of climate change. [68]

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 ...
The soil allows the crops to absorb the mercury, which humans ingest. Animals eat the grass which has absorbed the mercury and again humans may ingest these animals. Fish absorb the mercury from the water, humans also ingest the fish and drink the water that have absorbed the mercury. This increases the mercury levels in humans.
Humans are exposed to toxic chemicals and microplastics at all stages in the plastics life cycle. Microplastics effects on human health are of growing concern and an area of research. The tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water, food, and human tissues.
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.
The research found lower and middle income countries were the most polluted, while rubbish dumping along river banks, inadequate waste water infrastructure and pharmaceutical manufacturing and ...
