There is an important petition posted at Avaaz.org to the CEO of Yahoo, Marissa Mayer asking that she institute policies at Yahoo that Google and Amazon have already instituted: specifically, stop selling ivory! Yahoo needs to feel pressure from all of us to do the right thing by not allowing the sale of ivory on their website under any circumstances.
