Have a blissful day.
Here is a bit of contested evidence on the topic, specifically the part about suitable environments for life.From the tone of your reply I gather that any offense I may caused to you has blown over, and I am glad for that. I feel like you made an earnest attempt to explain your position (thanks again) and I don't mean to kick a dead horse, but I still don't get it. It seemed as if you were seeking inclusion of rocks, volcanoes, and such into the ranks of the living (or, near-living?). While some might find nobility in that, it seems to me that it would be counterproductive to what I perceive to be your motive. Vegan, meaning you don't hurt animals; I applaud your conviction. And you love mountains and rocks too; again, laudable. But if you managed to convince someone that a big mossy stone holds the same biological value as a dog, what does that mean for the dog? You already apparently have enough trouble convincing folks that "dogs are people too" without having to contend with "rocks are dogs too."
The rest of what you said I get. There are definitely some differences of opinion among different folks about what among nature deserves respect, and there is definitely some baggage. But it should not be allowed to water down the science. The science is the only concrete thing any of us have to fall back on. Science doesn't (or, isn't supposed to) have baggage. The philosophical quandaries like, "why is it ok to commit genocide on mosquitoes but not kittens?" and "why is it ok to pee on a tree but not a horse?" and "why is it a crime to kill an unborn sea turtle but not an unborn human" are all important issues that science can't help us with, and appealing to science or trying to bend it to support a philosophical viewpoint is folly indeed.
And that is exactly the exception I take with the quoted sections of the biology textbook in the OP. It was utter nonsense, scientifically speaking. Maybe it had merit in some other book, but not in that one.
Can we agree that mountains are important and valuable (more important and more valuable than a lot of the humans that are allowed to walk over them) without trying to classify them with a taxonomic rank?
I find it very interesting that life can spring from nothing more than minerals, heat and water. Look what is happening here: a volcano is literally spewing out the basic ingredients for life. So, if we can agree the volcano, deep sea vent or whatever, brought the basic ingredients together... does it not beg the question: why did the volcano (and by extension, Earth) do it in the first place? I'm finding it increasingly hard to believe that the transition happened at the location of the vent etc. when the chemistry shows the process didn't start there.
