What actions can individuals take to improve air quality?

Using public transportation and reducing energy consumption encompasses key actions that individuals can take to improve air quality. When people opt for public transportation, they reduce the number of personal vehicles on the road, which decreases emissions of harmful pollutants such as nitrogen oxides and particulate matter. This shift can lower traffic congestion and subsequently the overall vehicle emissions that contribute to smog and respiratory problems.

Additionally, reducing energy consumption often involves adopting practices such as turning off lights when not in use, using energy-efficient appliances, and conserving heating and cooling. These actions lead to decreased demand for energy production, which is often reliant on the combustion of fossil fuels. Lower energy consumption can thus significantly reduce air pollutants and greenhouse gas emissions associated with power plants.

In contrast, other choices involve actions that would likely worsen air quality. For example, driving more personal vehicles or increasing the use of fossil fuels would elevate emission levels, while burning more waste could release toxic substances and particulate matter into the atmosphere, further degrading air quality. By focusing on public transportation and energy conservation, individuals can effectively contribute to a cleaner and healthier environment.
