A 2019 UN report assessing global biodiversity extrapolated IUCN data to all species and estimated that 1 million species worldwide could face extinction. [38] [39] Conservation of a select species are often prioritized on several factors which include significant economic and ecological value, as well as desirability or attractiveness. [40]
Conservation biologists research and educate on the trends and process of biodiversity loss, species extinctions, and the negative effect these are having on our capabilities to sustain the well-being of human society. Conservation biologists work in the field and office, in government, universities, non-profit organizations and industry.
Forests harbour most of Earth's terrestrial biodiversity. The conservation of the world's biodiversity is thus utterly dependent on the way in which we interact with and use the world's forests. [78] A new method used in 2011, put the total number of species on Earth at 8.7 million, of which 2.1 million were estimated to live in the ocean. [79]
Successfully achieving sustainable forest management will provide integrated benefits to all, ranging from safeguarding local livelihoods to protecting biodiversity and ecosystems provided by forests, reducing rural poverty and mitigating some of the effects of climate change. [86] Forest conservation is essential to stop climate change. [87] [88]
At a national level, the Environment Protection and Biodiversity Conservation Act 1999 is the primary environmental protection legislation for the Commonwealth of Australia. It concerns matters of national and international environmental significance regarding flora, fauna, ecological communities and cultural heritage. [ 54 ]
A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. [1] [2] Norman Myers wrote about the concept in two articles in The Environmentalist in 1988 [3] and 1990, [4] after which the concept was revised following thorough analysis by Myers and others into "Hotspots: Earth's Biologically Richest and Most Endangered ...
As a tropical continent with substantial anthropogenic development, Africa is a hotspot for biodiversity [14] and therefore, for human-wildlife conflict. Two of the primary examples of conflict in Africa are human-predator (lions, leopards, cheetahs, etc.) and human-elephant conflict.
Wildlife trade is a serious conservation problem, has a negative effect on the viability of many wildlife populations and is one of the major threats to the survival of vertebrate species. [8] The illegal wildlife trade has been linked to the emergence and spread of new infectious diseases in humans, including emergent viruses.
