Last week on the way to home on the my smartphone, I read one article about a green park event. It was really amazing. In the park near my house is going to giving gave away free recycle bags because there are the park is full of garbage that the vistors throw it away in the park. So that visitors who are willing to visit the park had to have recycling bags for their garbage, if they don't have it, they're it's not allowed to enter the park. So, eventually the park became a really clean place and it's a really lovely place where everyone likes. I think the decision of the park office was a very good idea and recommendable. I hope other parks have the same practice as this.
