One effective way of tackling the problem is demanding money from tourists. For example, in some Japanese tourist attractions, if people want to enter the territory, they will have to pay a reasonable and affordable amount of money for it. Since there are many tourists, raising money this way is not difficult. After having received the money, the Japanese government begins to set up infrastructure, such as litter-bins. Thus, fewer people will be leaving their garbage on the ground. The adequate use of money, therefore, can considerably reduce the amount of trash being left.
