Bioaccumulation of Toxins:
Bioaccumulation of toxins happens when pollutants, such as heavy metals and pesticides, build up in the bodies of living organisms over time. For instance, studies by the Environmental Protection Agency have shown that fish in polluted waters can accumulate high levels of mercury. This accumulation can lead to health issues and affect reproductive success, ultimately threatening species survival.
Altered Food Sources:
Altered food sources result from pollution affecting organisms at various trophic levels. Contaminated water can lead to declines in aquatic plants and fish populations. According to a report by the United Nations Environment Programme, the decline of phytoplankton due to pollution impacts the entire marine food web. Less food availability causes starvation and reduced reproductive success in dependent species.
Reduced Reproductive Success:
Reduced reproductive success occurs when pollution interferes with the breeding and development of offspring. Endocrine-disrupting chemicals can affect reproductive hormones in animals. A study by the University of Exeter in 2015 found that fish exposed to these contaminants exhibited lower reproductive rates. This decline can have long-term impacts on population viability.
Climate Change Interactions:
Climate change interacts with pollution to exacerbate survival threats. Increased carbon emissions lead to higher temperatures and ocean acidification, which compounds the effects of pollutants. A study from the Intergovernmental Panel on Climate Change indicates that these dual stressors can significantly reduce biodiversity across ecosystems. Species already stressed by pollution may have decreased resilience to climate change impacts.
