Nature Adapts to Changes in the Short Term

Given enough time, nature adapts to what is thrown in its path and evolves accordingly. We tend to throw a spanner in the works as humans because we make things happen on very short time scales that then really upset the apple cart. But yes, nature can adapt and generally does adapt. What's the doctor's thoughts on electric cars? If we all convert to electric cars, will it make a difference to the environment? Seeing that the batteries are a mission to manufacture, won't we be better off just ticking to petrol cars? So layman with that question.
