As we all konw the mainstream approach methods focuse on "consume differently", while alternative focuse on "consume less". But in my opinion this two definitions are related.
For example, when government put an levy on the plastic bags, people will change to use other material bags. This can be identified as "consume differently". However, this change also means the consuming of plastic bags becomes less.
So how can I identified the government levy? Is it a mainstream one or alternative one?
