Sounds like a meme, but it's true https://www.theatlantic.com/science...wgGegtCNkKKy5-sH9W-JxGeF4PvwoAck-T3WyiMj2_GCg The Air Really Was Cleaner Under Obama Pollution is up nearly 14 percent under the Trump administration.
And this is a surprise? China, Russia and India, along with a host of other emerging nations belching out pollution like there's no tomorrow. It also goes to prove that until these nations are held to account it matters little what the United States does to make further cuts beyond the dramatic reductions we have already made over the past several decades. Only a lefty could twist this into an America is the bad guy while completely ignoring that it is the idiot policies of the left which let all these other countries off the hook which is the major contributing factor.
Per capita the US pollutes more than the countries you mentioned. In any case, what you said does not make sense. Any reduction in pollution is beneficial. By your own logic, small countries shouldn't bother doing anything because hey, look at what America is doing.
