Subject: Increasing problem of air pollution

Sir,
Through your esteemed newspaper, I would like to highlight the increasing problem of air pollution in our city. The smoke from vehicles and factories has made the air poisonous. People are suffering from breathing problems.

The authorities must take strict steps: plant more trees, check vehicles, and control industrial waste. Public awareness is also necessary.

I hope this issue will be published for immediate action.
