As a reader of “Limits to growth”, I rate the Building article “More than we can handle” (15 June, page 40) as a living testimony to the tipping point that the Club of Rome forecast all those years ago.

The irony is that our command economy, which has limited its own population growth, seems to be leading us over the top. Now we have two international sporting events accelerating us past the tape.

It is sad that the building industry seems to be celebrating its apparent release from any technological constraints by producing jewels of non-sustainability – glass houses to nurture architectural and corporate egos – when it is equally capable of leading us towards a sustainable future using the very same technological prowess.

The cover picture captures the dilemma perfectly: man crushed by his own “success”.
