One of these problems that is able to be heard, but not seen, is noise pollution. One cannot go around pointing out the noise pollution that affects everyone, everyday. Noise is not something that can just be taken and buried underground and won't have to messed with anymore. It is something that must be taken care of by simply producing less of it. Noise is around everywhere.
Some places have more noise than others do.
There seems to be a direct connection between the amount of noise a person is around, and their way of life. Babies are being hurt by noise. Children are being hurt by noise. Maybe if everyone knew how they were affecting everyone else with their noise, some of it would cease. It would take the help of everyone to change these problems.
