We are doing many things. We are littering and continuously using CFC's.
the most common action taken to help reduce and prevent noise pollution is planting dense hedges near roadways.
the government is doing anything about this but it is killing the animals that live in the soil,and the things that eat the soil
I don't know man, I live in Dubai and I haven't seen them doing anything for a while now.

Sadly, barely any Chinese companies are doing much to prevent air pollutants in China. The Chinese rivers in china are shocking if you look at how much stuff they dump into them, they are practically toxic, and they are brown and disgusting from a ton of different pollutants. As to air pollution, there has been monitored pollutants in the air that are blown all the way into Alaska and filling the air. One city, Dailang, along the coast from Beijing, has received many, many awards for cleanest city, and best evironmentalists, and many things that are good for the einvironment. American organizations like John Deere and many other buisnesses are also doing things to prevent air pollution in China the best they can.
Nothing
I really believe that we can make a solution and apply it, you know. But then most us don't really understand what are the results of doing these things to the environment, deteriorating it time by time. We can prevent environmental polltuon simply by reusing, reducing and recycling things. Disposing our trashes well to their places and disposing harmful toxics to their right places so that it won't harm our trees, rivers and of course our wildlife. :))
People are discontinuing activities that cause air pollution. They are installing equipment that cleans air pollutants before they are released into the air.
We could help stop pollution by doing a clean up or maybe just not littering youreself or you could be more respectable of water and just throw your garbage in the trash.
