The passive voice is used to show interest in who or which experiences the action, rather than who or which performs the action

The important thing or person becomes the subject of the sentence:

This road is used frequently    interest in the road, not in who uses it

The house was built in 1900    interest in the house, not in who built it

Kira will be adopted soon    interest in the dog, not in who will adopt her

The passive voice is used because:

the subject of the verb is the recipient of the action of the verb, not the agent
The subject is unknown or unimportant or common knowledge

ACTIVE VOICE

SUBJECT – VERB – DIRECT OBJECT

Humans- enslave- animals

PASSIVE VOICE

DIRECT OBJECT – VERB TO BE – PAST PARTICIPLE – BY – SUBJECT

Animals- are- enslaved- by- humans
