China still dumps insane amounts of waste into the ocean and has almost no regulations to combat their giant smog cloud, so "leaps and bounds" is a pretty stupid thing to say. Kind of funny how they have the cancer-inducing smog in their cities but people want to say we're the worst when it comes to emissions.
Not only that, but we regulate our emissions and dumps. We replant forests. The only way the west can do anything extra to fight man-made climate change is start sterilizing third world countries, you know, the ones doing the deforesting and such. But that'd be bigoted so nvm
