Air quality improvement refers to the efforts and measures taken to enhance the cleanliness and safety of the air we breathe. This can involve reducing pollutants such as carbon dioxide, nitrogen oxides, and particulate matter that can harm human health and the environment. Strategies include promoting the use of renewable energy sources, improving public transportation, and implementing stricter regulations on industrial emissions. Community involvement plays a crucial role in air quality improvement. Individuals can contribute by using bicycles or electric vehicles, reducing energy consumption, and supporting local initiatives aimed at planting more trees. These actions help lower pollution levels and create a healthier atmosphere for everyone.
