Habitat loss and fragementation
humans has led to extinction of a particular species :
• from one of the "evil quartet" , habitat loss and fragementation is one of the major cause driving animals towards extinction .
• for example - Amazon rain forest - covering more than 14% of earth surface, now are no more than 6%.
• Amazon rain forests calles as "lungs of planet" are probably been cut for soya bean cultivation and raising beef cattle.

Answer:
Yes, there has been such a situation where different types of parasites and disease-causing micro-organisms would want to be eradicated from the planet. Scientists are working extensively to fight and wipe them out completely as these microbes are harmful to human existence and have been successful in eliminating small pox from the Earth through the successful use of vaccination which shows how humans deliberately want to makes these species extinct. Some other programmes aiming at eradication are for Hepatitis B, polio vaccinations etc to eliminate those microbes that cause diseases.
