Need a reminder? The key ideaShow
Five mass extinctions have happened, and a sixth is in progress at a rate 100 to 1000 times faster than before humans. In the last 500 years, 784 species have gone extinct: 338 vertebrates, 359 invertebrates and 87 plants. If a share of the species is left after years, the share kept each year is (not in the NEET syllabus).
