Yes I agree that It's nothing compared to other payment method, the data that you've posted on the OP only in a one country, how about the rest of the world? Paper usage, electricity for the ATM machine, etc. Well bitcoin is nothing, it might bring impact to the enviroment but I think not too much, it doesn't need paper, plastic card, ATM machine, etc. We're only use electricity where we have an alternative such as renewable energy.
