This is a lovely idea, but totally ignorant of global demography[1]. By 2100 there will be >3 billion people living in India and central Africa. Centra Africa in particular will show some of the greatest population growth. There will be another 300 million people living in the Congo, which is one fifth the size of the USA and a nightmarish war zone most of the time. There will be a stunning 600 million more people in Nigeria, which is even smaller. The irony is that these people will be mostly-vegetarian, use renewable energy and travel by bike, just not by their own choosing. Sheer numbers however will ensure global consumption continues to increase rapidly.
I don't know what the solution is, but the lifestyle choices of the Western world will become increasingly irrelevant.
