-For me, I feel very sad to see that the rivers are polluted, very upset. I grew up in a beautiful place with green hills and clear river. I believe we should protect these rivers, so the next generation would still have a chance to develop a close relation with them, could swim in them, play in them, I mean enjoy it.

-I worried, perhaps Chinese authorities, like western democratic leaders, think that we can fix this. We can do whatever damage we want to the environment, but science and engineering would be able to resolve it in the future. What if we can't? What if the damage we've done and we're doing still is irreversible? And what we've left, a completely destroyed environment to futurn generations. That would be completely immoral.
