Making something with less impact takes more effort. Filters/knowledge you name it, does not come cheap. It is not the amount of resources it is the process of turning resource into product. A cotton sweater is cheap. But if you want to make cotton sweater in a greener process, then you need water cleaning systems, maybe different paint (which is also more expensive).
