We need clean air to breathe well. The problem is that contaminants can mix into the air and damage our respiratory system. Infants and the elderly are particularly vulnerable. Those with existing lung diseases and allergies are also prone to health issues. We need to lessen these harmful contaminants by passing laws targeting the biggest offenders such as factories and automobiles. Inside our homes, we can implement Dust control by maintaining the cleanliness of A/C filters and using UV lights.
