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

Yes, there are various kinds of parasites and disease-causing microbes that we deliberately want to eradicate from the Earth. since these micro-organisms are harmful to human beings, scientists are working hard to fight against them. Scientists have been able to eliminate small pox virus from the world through the use of vaccinations. This shows that humans deliberately want to make these species extinct. Several other eradication programmes such as polio and Hepatitis $B$ vaccinations are aimed to eliminate these disease-causing microbes
