The Taliban are burning musical instruments in the name of morality. It is an assault on all culture The sounds of Afghan history are being erased to prevent music’s ‘moral corruption’ of the Afghan people. We can help keep Afghanistan’s music alive.

Jevons explicou há quase século e meio que não é a “eficiência energética” que reduz o consumo, pelo contrário. Para limitar a procura por nova energia seria necessário a imposição de ‘caps’: limitar quer as emissões (p.ex. lúmenes, no caso da luz) quer o consumo energético (p.ex. limite Wh/ano).2/2

Dos detractores destes mega-projectos diz-se que querem sol na eira e chuva no nabal (leia-se: energia sem impactos). Mas, enquanto não houver um teto (limite) no consumo energético, não haverá território que chegue. Reduza-se consumo e usem-se alternativas com menor impacto. 1/2
