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]
They kill not only targeted organisms, but also non-targeted organisms in the process. Pesticides are released into the natural environment intentionally by people who are often unaware that these chemicals will travel further than anticipated, Hatakeyama et al. as cited in. [ 6 ] Thus, pesticides largely affect the natural communities in which ...
[4] [5] Biological hazards, also known as biohazards, are organic substances that pose a threat to the health of living organisms, primarily humans. This can include medical waste, samples of a microorganism, virus, or toxin (from a biological source) that can impact human health. Biological hazards can also include substances harmful to animals.
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.

Cases of a dangerous and highly fatal bacterial infection have reached record levels in Japan, official figures show, with experts so far unable to pinpoint the reason for the rise.
A biological hazard, or biohazard, is a biological substance that poses a threat (or is a hazard) to the health of living organisms, primarily humans. This could include a sample of a microorganism, virus or toxin that can adversely affect human health. A biohazard could also be a substance harmful to other living beings. [a]
Drinking water from nearly half of U.S. faucets likely contains “forever chemicals” that may cause cancer and other health problems, according to a government study released Wednesday. The ...
