We watched seven worlds one planet today with DCs 8 and 5 today. The eldest was shocked by the deforestation and melting of ice caps etc and wants to do something.
His first idea was "Ask the manager of the tree cutting company to stop" 
Obviously this won't work so I'm here asking for ideas that we can quite easily implement to do our bit. I've started explaining to him about our carbon footprint etc and sustainable palm oil.
WWYD/have you done as a family?
