Difference between qe believed the practice is unsustainable and it ia believed the practice is unsustainable
Answers
In ‘We believe,’ in the active voice, the speaker takes responsibility, declaring his or her belief, which represents the belief of certain other people, that the practice is unsustainable. We must rely on the credibility of the speaker and the group as to whether the practice should be considered unsustainable.
The second sentence, in the passive voice, doesn’t say exactly who believes this but implies that this is a common belief. Maybe it is a common belief, maybe it isn’t; again, we have to rely on the credibility of the speaker. Or maybe the speaker just wants to avoid responsibility or is trying to give more weight to the belief than it deserves. Maybe the speaker shares this belief, or maybe the speaker doesn’t share it but is citing it in order to refute it.
