Due to uncleanliness, we can suffer from diseases and there are disadvantages.
First, if our house is unclean or dirty then it does not look good. Any visitors do not like the look of it. Even we ourselves do not feel happy being there.
Secondly, if the house is dirty, it becomes difficult to save ourselves from insects, bacteria,flies, mosquitoes and other harmful organisms. We may get diseases. So our health, time and money will be wasted.
Thirdly, dirt smells. It is often difficult to walk on roads nearby the huge waste bins. So we cannot stay like that for long.
If many people cannot do their duties properly and fall sick, it is a wastage of money and resources at the national level.
Only advantage one gets by not cleaning regularly or leaving things as they are, or by waste around every where, is the time and joy derived from laziness. But we may have to pay more price by this laziness.
So it is the best to be clean and keep the surroundings hygienic. Swachch Bhaarat and clean India drives are giving us the same message.
