The trouble is we're putting a quadruple sqeeze on this poor planet, a quadruple sqeeze, which, as its first squeeze, has population growth of course. Now, this is not only about numbers; this is not only about the fact that we're seven billion people committed to nine billion people, it's an equity issue as well. The majority of the environmental impacts on the planet have been caused by the rich minority, the 20 percent that jumped onto the industrial bandwagon in the mid-18th century. The majority of the planet, aspiring for development, having the right for development, are in large aspiring for an unsustainable lifestyle, a momentous pressure.
