Jul 4, 2024 · Biodiversity loss, the reduction in an area’s biodiversity (the number of genes, species, individual organisms, or ecosystems) expressed by species loss, population declines and reductions in the genetic diversity within a species, and the collapse of biological communities.
Biodiversity is rapidly declining worldwide, and there is considerable evidence that ecosystem functioning (e.g., productivity, nutrient cycling) and ecosystem stability (i.e., temporal...
Mar 16, 2023 · Not only does biodiversity loss impact individual species, but it also alters their symbiotic interrelations with other species and their habitats. In turn, ecosystem functions and aforementioned services are disrupted, with widespread consequences for humans and other life on Earth.
Jun 3, 2015 · There is growing concern about the health consequences of biodiversity loss. Biodiversity changes affect ecosystem functioning and significant disruptions of ecosystems can result in life sustaining ecosystem goods and services.
Biodiversity underpins the health of the planet and has a direct impact on all our lives. Put simply, reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease, and where fresh water is in irregular or short supply.
Key areas of human activity causing biodiversity loss include: Deforestation. Tropical rainforests are particularly rich in biodiversity and are being destroyed. Habitat loss through pervasive, incremental encroachment such as that caused by urban sprawl.
Jun 6, 2012 · In this Review we ask how biodiversity per se—that is, the variety of genes, species, or functional traits in an ecosystem—has an impact on the functioning of that ecosystem and, in turn, the ...
Jul 4, 2024 · Economic and societal effects. Biodiversity loss affects economic systems and human society. Humans rely on various plants, animals, and other organisms for food, building materials, and medicines, and their availability as commodities is important to many cultures.
May 18, 2018 · Biodiversity loss is caused by a range of different pressures, from habitat loss due to agricultural expansion, pollution or desertification to invasive alien species and climate change. At the root of every issue is one common thread: the unsustainable use of land and resources.
How is climate change affecting biodiversity? The main driver of biodiversity loss remains humans’ use of land – primarily for food production.
