The passive voice is used to show interest in the person or object that experiences an action rather than the person or object that performs the action. In other words, the most important thing or person becomes the subject of the sentence.
Sometimes we use the passive voice because we don't know or do not want to express who performed the action.
The passive voice is often used in formal texts. Switching to the active voice will make your writing clearer and easier to read.
Passive | Active |

Our planet is wrapped in a mass of gases. | A mass of gases wrap around our planet. |
Waste materials are disposed of in a variety of ways. | The city disposes of waste materials in a variety of ways. |
If we want to say who or what performs the action while using the passive voice, we use the preposition by. When we know who performed the action and are interested in him, it is always better to switch to the active voice instead.
