China, Cheng Du had workers spraying green dye on the grass which was turning yellow. They did this to let passers-by think that the grass are healthy. Some people stepped on the grass and their shoe became green. This dye is very powerful and is not toxic. It will last for ten to fourteen weeks and is not washed away by the rain. Some people said that they should use this money to build some schools instead of dying the grass
I think that the workers should not dye the grass. Though it is non-toxic, but it is still harmful for the grass. They really should spend the money on building schools or doing something to help the country instead of buying the dye just to make people think that the grass is still healthy.
