Keeping your environment clean is a thing that should be taken with all seriousness, even if you are too busy to carry out the task by yourself, you can get people to do it for you.
Keeping our environment clean helps us to stay healthy, because germs and pathogens do not have right to stay in a neat environment.
Since health is regarded to be wealth, then we have no other option than to maintain a good, neat and healthy environment as this will help us avoid sickness in whatsoever form it comes.
A clean environment is equivalent to a good life and a life free from irrelevant and unnecessary spending as most people spend all that they make on treating illness caused by diseases which occur from a dirty environment.
Keeping your environment clean is not something you avoid because your neighbor is avoiding it too, you have to do it for the sake of your health and for yourself.
