I think the actions should go on both producers and consumers. Taxes, and also mentality changes, in my case, I produce almost no garbage, because I eat fruit foraged outside, and other local organic food. My only garbage in a year is: 10 rice plastic bag (5kg bags), a toothpaste tube and a toothbrush, a few soap bars plastic wrappings. That's all. That yearly volume you see, that's what most people produce in one day in developed countries
