" This is an excellent and broad examination of the impact of a key social trait on the environment. Such integrated, interdisciplinary studies are rare. The work is of broad general interest and the extremely interesting findings extend the ground-breaking research of the corresponding author on the impact of household dynamics on the environment.[Nature 421(6922):530-533] "
" This is a surprising conclusion, in that it is to an extent obvious, but has clearly not been considered sufficiently in an environmental context.
I consider that this finding definitely needs to be brought to wide public attention, and that it will be very favorably considered in the important fields of thought to which it applies."
