Why can't P&G please deforestation activists?

Procter & Gamble Co. promised decisive action in 2014, after Greenpeace protestors hung 60-foot banners from the company’s headquarters building. “Head & Shoulders: Wipes out dandruff and rain forests,” one banner proclaimed. It was a reference to P&G’s use of palm oil as a key ingredient in shampoo and liquid detergent. The widely used oil comes from plantations that replaced tropical forests in Malaysia and Indonesia.
