LOSS OF BIODIVERSITY

 

The loss of species, ecosystems or genes is termed as a loss of biodiversity. The biological wealth of the planet is declining rapidly. The IUCN Red List documents the extinction of 784 species ( including 338 vertebrates, 359 invertebrates and 87 plants) in the last 500 years. In the last 20 years alone, we have witnessed the loss of more than 30 species. As per the Living Planet report:

  • The present rate of extinction of species is up to 100 to 1000 species extinction per 10,000 species in a duration of 100 years. This is almost 1000 times more than the natural rate of extinction.
  • The living planet index, which measures the biodiversity abundance levels, is showing a persistent downward trend. On average, monitored species population has declined by 58% since the year 1970.
  • In tropical forests, there has been a 40% decline of species since the year 1970.
  • Whereas in temperate grasslands, species population has declined by 18% and in freshwater habitat, species population has declined by 81% since the year 1970.
