How would you decide if given the choice between changing your lifestyle or wiping out 25% of the world's species?

This is a decision that we keep putting off, perhaps in the belief that some technological solution will be thought of. In the meantime we are engaging in a mass extinction. I am thinking that many people may not really care. They may be thinking, What did polar bears and pandas ever do for me?

There is a possibility that we may end up with the worst of all worlds. Only after eliminating other species will we be forced to change our ways due to limited resources and global warming. While it does not take much time to remove species, it takes considerably longer for new ones to evolve.
