Such threats to biodiversity may cause the extinction of many species. In May 2020, the European Union published its Biodiversity Strategy for 2030. For information on reusing text from Wikipedia, please see the terms of use. Furthermore, the diversity of forest ecosystems (in both physical and biological features) results in high levels of adaptation, a feature of forest ecosystems which is an integral component of their biological diversity. [38], The period since the emergence of humans has displayed an ongoing biodiversity reduction and an accompanying loss of genetic diversity. [225], A recent study predicts that up to 35% of the world terrestrial carnivores and ungulates will be at higher risk of extinction by 2050 because of the joint effects of predicted climate and land-use change under business-as-usual human development scenarios. "[93], Biodiversity is the result of 3.5 billion years of evolution. Increasing atmospheric carbon dioxide certainly affects plant morphology[218] and is acidifying oceans,[219] and temperature affects species ranges,[220][221][222] phenology,[223] and weather,[224] but, mercifully, the major impacts that have been predicted are still potential futures. Due to mindless and unsustainable resource use, once productive forest and grasslands have been turned into deserts, and wastelands have increased all over the world. Planned diversity includes the crops which a farmer has encouraged, planted or raised (e.g. The core threats to biodiversity are human population growth and unsustainable resource use. [175] This figure indicates unsustainable ecological practices, because few species emerge each year. The number of species involved in such pursuits is in the tens of thousands, though the majority do not enter commerce. Threats of Biodiversity. [61] Wilcox's definition was "Biological diversity is the variety of life forms...at all levels of biological systems (i.e., molecular, organismic, population, species and ecosystem)...". Protected areas are meant for affording protection to wild animals and their habitat which also includes forest reserves and biosphere reserves. [209][210][211][212][213], Genetic erosion and genetic pollution have the potential to destroy unique genotypes, threatening future access to food security.

[74] Areas with dense human populations and intense agricultural land use, such as Europe, parts of Bangladesh, China, India and North America, are less intact in terms of their biodiversity. As climate warms, species will migrate towards higher latitudes and altitudes in both hemisphere.
