Query: Wasteful In Every Way

We purchased this Keurig to replace an old grind & brew coffee maker that quit. After about 90 days, the Keurig began to fail to pump water from the reservoir into the water-heating tank. The pump would run and run and run and then the whole thing would shut itself off. It was sporadic at first, maybe once a week, then it was every day, then it was every time we tried to use it, until it wouldn't work at all. So we stopped using it. I don't feel all that badly because I was already regretting how wasteful the whole K-system was when it did work. The pods are expensive but not outrageously so unless it bothers you to tear through $.40 worth of plastic wrapper that goes directly to landfill, to brew $.15 worth of coffee grounds, for each cup of coffee. The world is a better place if we just don't use this thing, so we don't. I got the grind & brew running again and I have great coffee with a relatively clear conscience about our environment.
