clean air

Clean air refers to the atmosphere that is free from harmful pollutants, such as dust, chemicals, smoke, and biological contaminants, which can negatively impact health and the environment. When air is clean, it allows people to breathe easily, reduces health problems like asthma and respiratory infections, and supports ecosystems. Maintaining clean air involves reducing emissions from vehicles, industries, and other sources, as well as protecting natural areas that filter pollutants. Overall, clean air is essential for human well-being, environmental sustainability, and the quality of life.
