Two children should be limit, says this British green “guru.” What makes him a guru? Saying outrageous things that others should do, but not him personally. He has two children of his own; notice he didn’t say the limit should be one child. He and his kids taking up space and “footprinting” the world is OK, but others are a different matter:

I am unapologetic about asking people to connect up their own responsibility for their total environmental footprint and how they decide to procreate and how many children they think are appropriate….I think we will work our way towards a position that says that having more than two children is irresponsible.

He’s courageous enough to “pronounce the P-word,” but not courageous enough to pronounce judgment upon himself or limit his own “footprint” beyond what he finds personally appropriate.
