Mack, I don't know what Trump is doing pulling out from WHO, but it was a very poor decision on his part. WHO is essential for important purposes like creating standards based on public health data. For God's sake WHO cured smallpox!
Mack, I will have you know that the US is actually behind on climate regulations, not ahead. If those regulations are too much for you then you should go live in a hut in the woods, hunt and fish for all your food, and walk everywhere you go. Because the fact is that the US has contributed a lot to climate change, which means we need to contribute a lot to fix it. This is actually why we need agreements like the Paris agreement. It makes sure that multiple countries are doing their fair share. If China isn't doing enough for climate change, then an organization or deal between the US and China could really help.
