Can you think of a situation where we deliberately want to make a species extinct? How would you justify it?
Which of the following statements are correct regarding global and Indian biodiversity estimates and the challenges in their inventory? S1: The total number of plant and animal species described globally so far is slightly more than 1.5 million, according to IUCN (2004). S2: Species inventories are generally more complete in tropical countries, making global extrapolations of diversity figures more straightforward. S3: A significant impediment to completing India's biological inventory is the shortage of trained taxonomic manpower. S4: The time-consuming nature of documenting new species exacerbates the problem of species becoming extinct before their discovery and description. S5: Robert May's conservative estimate places the global species diversity at about 7 million, implying a substantial number of species remain undiscovered.
