Currently, the awareness to maintain cleanliness of the environment is very concerning. We are so indifferent to the cleanliness of our environment. That can be seen from our school environment which is still a lot of trash. Then who is responsible for it all? Cleanliness of our school environment is not only the responsibility of the school’s janitor, but it is responsibility of everyone who is stay in school such as students, teachers, and also staff at the school. We are all involved in keeping our school environment. The amount of garbage in our school is because we are lazy to dispose the trash in its place. We do not know that it would endanger our own health. The rubbish which is piling up can cause various diseases. For example: dengue disease because rubbish heap could be the breeding place of dengue mosquitoes.
