Human impact on the environment ... found that around 26% of the planet's terrestrial surface is devoted to ... The health impact of transport emissions is also of ...
This ultimately affects all living organisms that comprise an ecosystem. Ecotoxicology has been defined as a branch of toxicology that focuses on the study of toxic effects, caused by natural or synthetic pollutants. These pollutants affect animals (including humans), vegetation, and microbes, in an intrinsic way. [1]
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
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 trade-off between human health and the "health" of nature has been termed the "health paradox" [45] and it illuminates how human values drive perceptions of ecosystem health. Human health has benefited by sacrificing the "health" of wild ecosystems, such as dismantling and damming of wild valleys, destruction of mosquito-bearing wetlands ...
Extreme weather and its health impact can also threaten the livelihoods and economic stability of people. These factors together can lead to increasing poverty, human migration, violent conflict, and mental health issues. [7] [8] Climate change affects human health at all ages, from infancy through adolescence, adulthood and old age. [3]
Whole ecosystem disruptions will occur earlier under more intense climate change: under the high-emissions RCP8.5 scenario, ecosystems in the tropical oceans would be the first to experience abrupt disruption before 2030, with tropical forests and polar environments following by 2050. In total, 15% of ecological assemblages would have over 20% ...
Biodiversity loss has bad effects on the functioning of ecosystems. This in turn affects humans, [45] because affected ecosystems can no longer provide the same quality of ecosystem services, such as crop pollination, cleaning air and water, decomposing waste, and providing forest products as well as areas for recreation and tourism.
