About

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Over generations, all of the species that are currently alive today have evolved unique traits that make them distinct from other species. These differences are what scientists use to tell one species from another. Organisms that have evolved to be so different from one another that they can no longer reproduce with each other are considered different species. All organisms that can reproduce with each other fall into one species. Read more...

  • More than 2,000 terrestrial vertebrate species face a high risk of extinction from natural hazards, including hurricanes, earthquakes, volcanic eruptions and tsunamis, according to a first-of-its-kind study.
  • Nearly 70% of the high-risk species live exclusively on islands, highlighting the particular vulnerability of island ecosystems.
  • Only 15% of high-risk species have specific conservation plans in place, while approximately 30% have their entire known range outside protected areas.
  • The study calls for increased investment in habitat protection, restoration, captive-breeding programs and species translocation to help vulnerable species survive in an era of intensifying natural hazards.

A study identified 2,001 species (834 reptiles, 617 amphibians, 302 birds and 248 mammals) that have at least 25% of their habitat in areas experiencing high impact from hurricanes, earthquakes, volcanic eruptions and tsunamis.
