Know your air pollution number in America, because this is the question I get most asked about from my Chinese friends. Since China has major problems with air pollution it is commonly asked what is it like in the US. I honestly do not know what the air pollution level is in America. China has air pollution problems but we had the same air pollution issues in American during our industrialization in our history. It will improve which the government is addressing in this article in the below link. I remember in my youth visiting my cousins in New Jersey and the Hudson River was so dirty from all the chemical companies dumping in the river but it has improved greatly. Also I notice blue sky and the sun during Chinese New Year because the factories close for the holiday and it clears up the sky rather quickly. So if you want to converse with someone in China it is a good idea to know the levels from America so you can compare because you will notice it in China.
