Hello!
What you have so far is solid and straight-to-the-point. However, I would adjust it slightly in order to be more shocking to your audience.
Here is my suggestion: "Smog pollution is affecting earth's air quality and is causing the planet's temperature to rise at a rapid rate, which can be detrimental to all of earth's species if it is not controlled soon."
I am not entirely sure what your topic is or what you intend to persuade your audience into believing, so you can change what I have written into what works best for your essay. I would recommend adding an interesting/scary fact into it in order to convince your audience of the importance of your topic.
I hope this helps you! Have a great day!

Cisneros plays around with connotation and denotation with the word only by using the word in different ways. As in this example sentence, it says they are the only daughter, inferring that there is one female child, but they say they are only a daughter, inferring that they feel they can be nothing more than a daughter.
It basically translates to "Be at your best behavior!" or "Be ready at attention" depending on the scenario.
I know a website that can help you though. For more info, message me.
