Question

What is the scientifically sound estimate of global species diversity made by Robert May?

विकल्प

• Slightly more than 1.5 million species

• Nearly 45,000 species

• Around 7 million species

• Between 20 to 50 million species

Answer 1

Robert May, a prominent ecologist, provided a more conservative and scientifically rigorous estimate that places global species diversity at around 7 million species. This estimate is considered more reliable than extreme guesses that range from 20 to 50 million species.
