Biodiversity decline continues due to a rapidly expanding human population. The Phanerozoic is the current geological eon in the geological time scale, and the one during which abundant animal and plant life has existed. Biodiversity, the diversity of life on Earth, is essential to the healthy functioning of ecosystems. Today I will explain you what are the causes of biodiversity decline. It covers 541 million years to the present. Chytridiomycosis has irrefutably harmed amphibians. In addition, increased carbon dioxide causes acidification of the ocean, affecting creatures and plants that are sensitive to pH imbalances. Illegal … Biodiversity also plays an important role in drug discovery and medicinal resources. Genetic erosion in crop biodiversity is the loss of genetic diversity, including the loss of individual genes, and the loss of particular combination of genes (or gene complexes) such as those manifested in locally adapted landraces of domesticated plants adapted to the natural environment in which they originated. A biodiversity hotspot is a region with a high amount of biodiversity that experiences habitat loss by human activity. In May, the UN report on biodiversity broke it down into five main factors. As such, forest biological diversity encompasses not just trees, but the multitude of plants, animals and micro-organisms that inhabit forest areas and their associated genetic diversity. The loss of genes and individuals threatens the long-term survival of a species, as mates become scarce and risks from inbreeding rise when closely related survivors mate. Eight major causes of biodiversity are as follows: Habitat Loss and Fragmentation 2. Societal responses to the loss of biodiversity also involve trade-offs,and the elaboration of these will be essential in developing wiser environmentalethics and policy. Posted in Biology PPT, Ecology, Ecology PPT, Environmental Science and tagged Biodiversity Destruction PPT, Causes of Biodiversity Degradation PPT, Ecology PPT, Loss of Biodiversity, Threats to Biodiversity … Lack of Biodiversity As biodiversity decreases, there will … Our world’s population is increasing by millions each year. This article throws light on the ten major causes for the loss of biodiversity, i.e, (1) Destruction of Habitat, (2) Hunting, (3) Exploitation of Selected Species, (4) Habitat Fragmentation, (5) Collection for Zoo and Research, (6) Introduction of Exotic Species, (7) Pollution, (8) Control of Pests and Predators, (9) Natural Calamities, and (10) Other Factors. Biodiversity loss - Biodiversity loss - Ecological effects: The weight of biodiversity loss is most pronounced on species whose populations are decreasing.
