Bio-diversity is a term used and heard throughout the environmental and conservation sector and can be broadly defined as the variety of life on Earth, in all its forms and all its interactions. The term biodiversity was coined in 1985 – a contraction of “biological diversity”.
More formally, biodiversity is comprised of several levels, starting with genes, then individual species, then communities of creatures and finally entire ecosystems, such as forests or coral reefs, where life interplays with the physical environment. These myriad interactions have made Earth habitable for billions of years.
Estimates on the number of Earth’s current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86 percent have not yet been described.More recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described but…
The huge global biodiversity losses now becoming apparent represent a crisis equalling – or quite possibly surpassing – climate change. Rapid environmental changes typically cause mass extinctions. More than 99.9 percent of all species that ever lived on Earth are estimated to be extinct. According to a 2019 Global Assessment Report on Biodiversity and Ecosystem Services, 25% of plant and animal species are threatened with extinction as the result of human activity.
