I would think this would be an uncontroversial statement, they are a higher primate, but we are higher still. The loss of one of us is an even greater loss than one of them. But a lot of the sentiment and commentary surrounding the zoo incident where a Gorilla was shot seems to gloss over this basic reality.
Why?
A tranq would not have been instantaneous, the Gorilla is hundreds of pounds and dragging the kid by the leg, even if it did not intend any harm that was dangerous. The safest course of action once the kid was near the Gorilla was to take it out. This is not a feel good story, it IS tragic that such a creature was taken out, but that was a superior course of action to other less definitive tactics. Disagree? Why?
Some people are attacking the parent for having too many kids at the zoo, as if kids that are not leashed like dogs don’t EVER get loose even when they are solo. I even saw some comments (and UPVOTES) to the effect that since Gorillas are endangered, 1 of their lives was worth 70k of ours (apparently trying to normalize the relative population sizes of gorillas and human beings).
But this is all part of a larger poisoning of the mind where people treat animals as if they have just as much worth as a human being. They do not. Some get closer, dolphins, dogs, horses, great apes - either through greater intelligence of being cuter, others are further away either because of a less developed self awareness, or being grotesqueries like the sea lamprey, but to be AS valuable as a human being, you need to be on the same level as a human being.
ET would get just as much protection from me, because that is a fully sentient being at least as much as a human being if not moreso. But right now, we are the gold standard.
Who disagrees with this? And on what basis?
EDIT: To the last bit, there was an idea floated that part of the worth of a creature is tied to his level of sentience, this is a dangerous standard because we might come across a species in the cosmos that dwarfs our own sentience, are we then nothing more than an insect to be crushed in terms of our worth compared to them?
The way out of this problem is to set some threshold of sentience. This is an arbitrary line, some people might set it at the level of insects like some radical peta types, but I don’t have a solid argument about where to set this line/standard.
