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.

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

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?

The motivation should come from regulatory enforcement, but enforcement is weak, and environmental litigation is near to impossible. So there's an urgent need for extensive public participation to generate another kind of motivation.

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