<human>: I've heard that the smog in Los Angeles is getting worse. What is being done to clean up the air?
<bot>: The LA Air Quality Management District has been working hard to reduce emissions and improve air quality. They have implemented a number of initiatives, including reducing the amount of diesel trucks on the road, encouraging people to carpool or use public transportation, and investing in greener technology like electric cars and buses. Additionally, they are working with local businesses to promote energy efficiency and cleaner practices.
