There is a growing recognition of the importance of really bringing pollution under control.

Regulatory failings mean that the cost of breaking the law is far below that of obeying it - businesses are happier to pay fines than to control pollution.

Pollution is a serious one. Water pollution, air pollution, and then solid hazardous waste pollution. And then beyond that, we also have the resources issue. Not just water resources but other natural resources, the mining resources being consumed, and the destruction of our ecosystem.

Apple has made this commitment that it's a green company. So how do you fulfill your commitment if you don't consider you have responsibility in your suppliers' pollution?

I hope to see an integrated solution created to deal with both the local pollution problem and the global climate change problem.

People realised this is real pollution; it is not fog. Now everyone has to face the data and come out of their comfort zone.
