People who don’t flush toilets may have a disregard for basic hygiene and cleanliness norms. They may not understand the consequences of their actions, or they may believe that flushing is someone else’s responsibility. In some cases, it may also be a result of a lack of access to proper sanitation facilities or education about their importance. Regardless of the reason, not flushing toilets can create unsanitary and unpleasant conditions for others and can contribute to the spread of diseases.
