I don't think there will be a loss of value.
In my opinion, value refers to the beneficial relationship that the object can meet the needs of the subject, and it is a philosophical category that represents an effectual relationship between the attributes and functions of the object and the needs of the subject. Therefore, since the existence or destruction of non-sentient biota had no effect on other sentient beings. This, then, means that these non-sentient biotas have no exploitable value or beneficial effect on other sentient beings. Some might argue that the existence of these non-sentient biotas has intrinsic value. But I don't think these non-sentient biotas have the ability to recognize and understand the concept of value. Since they cannot perceive value, they have no intrinsic value at all. We think of non-sentient biota as having intrinsic value only because we start with our own thinking patterns that give us an understanding and an idea of the meaning of their existence.
