Question

In two to four short sentences (or in the form of a list), explain why Los Angeles has such serious air quality problems. Include at least three distinct reasons (this means that only one can be about sources of pollutants; the three reasons can each be about a pollutant source).

Answer 1

Answer:

- Large amount of activities generated by 33 million people

- Topography

- Gasoline and diesel powered engines

Explanation:

- Large amount of activities generated by 33 million people:

An average person normally produces a small amount of pollutants during normal and business activities but since there is a gigantic amount of people residing in Los Angeles (around 33 million people) personal pollution adds up to a big pollution source.

- Topography

Los angeles cities are built on plains and surrounded by mountains, they have a warm and sunny climate, this conditions prevent the air from circulating and trap air pollutants which makes Los Angeles cities prone to accumulate a higher amount of pollution.

-Gasoline and diesel powered engines

Gasoline and Diesel combustion release carbon dioxide polluting the atmosphere. Tons of pollutants are formed every day in Los Angeles by electricity industries, gasoline terminals, refineries, cars, trucks, trains and boats which main source of energy is carbon combustion.
