Italiano Sovrappopolazione Umanita'


Un inquietante elogio della Cina che con la sua politica del “figlio unico” ha evitato la nascita di 400 milioni di persone, è stato scritto da Jonathon Porritt, figura di primo piano dell’ambientalismo britannico, consigliere del governo laburista e del principe Carlo. Così si fa strada una mentalità ideologica che negli esseri umani non vede una potenzialità o una speranza, ma soltanto emettitori di CO2 e consumatori di risorse. Dove stiamo andando?

Dear Editors

It’s very good for Paul Krugman (“The Politics of Spite“, Oct 5) and Tom Friedman (“Where Did ‘We’ Go?“, Sep 29) to lament the decay of contemporary US political debate into mutual accusations and “puerile spite“. Could anybody therefore please explain if those are the same Paul Krugman and Tom Friedman that regularly describe in unyieldingly negative tones anybody not sharing their opinions on global warming/climate change?

First Law of Planetary Building

First Law of Planetary Building: no two planets will ever be alike.

Corollary #1: if two planets are almost identical, then at least one of them will have at least one outrageously peculiar feature.

Corollary #2: Universes made of perfectly identical planets are not allowed.

The First Law is manifest in the fact that each planet in the Solar System and elsewhere appears to be a unique, very specific experiment with peculiar conditions that are never repeated elsewhere. Even single satellites are all very different from one another. And if you want to top strangeness, how about Corot-7b with its clouds of minerals?

One objection could be raised about Venus and Earth, or Uranus and Neptune, as both couples look like made of identical twins. However, Venus’s hellish atmosphere and very slow, retrograde rotation are truly outrageously peculiar features; and Uranus basically lies to one side (hence corollary #1).

Corollary #2 is necessary otherwise the First Law is invalidated. It seems plausible, since the number of universes is large but not infinite.
