If I could change something about Japan...

Hello!(*^∪^*)
If I could change something about Japan, I would want people to stop to throw away trash along the street.
It is because I feel sad when I see trash near some beautiful flowers.
I always see trash along the street when I go to school.
I do not know why they don't throw away trash. I think it is an irresponsible act.
If Japanese people stop to throw away trash along the street, Japan will be a better country.
