Even when we see a great green field and stunned by its beauty we start running around enjoying it we step on living things. When we breath we breath living things as well.
It is impossible to exist as far as I know without burning/kiling. The key I think is to be conscious about it; when you are conscious about it your experience is different, you know the full balance, you know and accept with humbleness, your future decisions will be in tune with you the conscious one.
