During school today I was shown the first video below, advertising Earth Hour. It struck me that the primary claim, ‘The need for urgent action is now indisputable’ in some quarters remains very questionable.
A possible TOK and Aim 8 teaching point? Does the very nature of the event highlight / ignores what could be done all year round? e.g. Why is Sidney harbour bridge decorated through the night? Yes the Eiffel tower looks pretty all lit up but…
I have therefore included a favourite video that sets out the precautionary principle with respect to global warming together with links to the Earth hour website and articles from The Economist and New Scientist as a starting point for possible discussion in your classroom.
