The official story is that the farmers are burning rice straw. It is unbelievable, unreasonable and criminal for one practice to harm the health of so many other people. It is also very bad for tourism. Not every tourist who comes here is rich. This is a once in a lifetime trip.
Some tourists save up for years to come here.
On the other hand, if a visitor has a bad experience, they will spread the word to others who will never come at all. Rice straw can be used for many things. It can be made into mulch or fertiliser. Maybe it can be used to make paper. I hope someone can use this by-product and thereby save our health.
