The point is, if everyone starts thinking to follow the same suit that you have suggested, where will everyone finds 'Others'?
No, I think the point is that there are 6.6 billion of us here now when there should really only be around 2 billion (best guesstimate at our current standard of living with just distribution of resources) assuming we want to be sustainable. We exceeded the carrying capacity of the Earth back in the late 1980s, based on EFA, which is extremely conservative (e.g., it doesn't factor in the needs of other creatures) and at our current growth rate of around 1.2% we'll double our current population in less than 60 years appropriating or liquidating more ecosystems and further increasing the loss of biodiversity and the life supporting ecosystem services. On our current path, we won't have to worry about where 'everyone' will find 'others' as there likely won't be many (any?) of us around. Neil
