Can you think of a situation where we deliberately want to make a species extinct? How would you justify it?

उत्तर

Yes, there are situations where we deliberately want to drive certain species to extinction. This argument is highly justified in the following way:

  • Target Species: This classification applies to causal organisms or pathogens that trigger deadly epidemic human diseases (such as the Polio virus, HIV, and Varicella virus).
  • Justification: Eradicating these disease-causing viruses is completely justified because they are extremely harmful to human health and survival. Furthermore, they do not play any beneficial role as decomposers or producers, and their elimination does not disturb the natural food chains or ecosystem stability.
