In my opinion, one country alone can't have much influence on it! Every country in the the world should work together to fight against climate change! If all of them take action, only then can we make it! Don't you agree? I am a Native Chinese speaker and I live in China. I'm a professional teacher and I teach English at my school. I 'm good at Chinese so I hope I can teach you! Come on! I'm looking forward to hear from you! I wasn't really sure what was your core idea here so I assumed that you were talking about the measures implemented globally to fight against climate change. Try to be a little more accurate when you want to present your arguments on a given topic. All the best.
