Pollution from animal manure can be used creatively. Instead of polluting landfills it can be used to produce electricity, filter water and power your car. This is what we call "clean energy".
Advertising makes you believe that buying stuff will make you happy, but minimalists disagree. My family and I are minimalists. This does not mean that we are hippies. It means that we are responsible consumers. There is nothing strange or mysterious about being a minimalist. (I don't care about buying what is in fashion or the latest version of "x". We buy what we need). Free of debts, we have more time to focus on meaningful activities. I also find that empty spaces open up my imagination and provide a “room” for my creativity.
