What I Learned During Earth Hour
A book and a wind-up torch. During Earth Hour, I learned the following: The origin of apples; A little about the last few months of Leon Trotsky’s life before being exiled; That I can still read a book in the dark with a torch (like I did as a child, under the blanket after bed time); And, thanks to @glasgow_kat, that petrochemical candles have much higher emissions than an electric light. Earth Hour is a fantastic way to highlight the problem of climate change in solidarity with people across the globe but it is not enough on its own. Switching the lights off on landmarks from Sidney Opera House to the Eiffel Tower to the Empire State Building for one hour is purely symbolic. Even switching them off permanently would be insignificant. The kind of reduction in fossil fuel use that we need to achieve would be more like everyone everywhere turning off the lights, heating, air conditioning, refrigeration, computers, televisions - everything for an hour. Not just once a year...
