I think your question is a philosophical one. What is the proper role of the human species in Earth's ecology? It sounds like you think "might makes right", and that any choice which maximizes human life expectancy is the right choice.
It saddens me to think that people are willing to push so many living organisms to extinction, just to make our lives a little more comfortable and last a little bit longer. I think it is important to protect life, in all its forms.
