dimreepr Posted February 20, 2020 Posted February 20, 2020 But we (life) are an integral part of the planetary system and we (life) depend on that system; I'm not sure there's a qualitive difference between the two. The ecosystem that is me, may as well be a planet to the life that depends on me; even a virus, that is trying to kill me, needs me to live, or at least provide a suitable enviroment. 1
Prometheus Posted February 20, 2020 Posted February 20, 2020 There is a sense in which the bee and the flower are a single organism - but it's generally more precise to refer to it as an ecosystem, at least in scientific discourse. I personally consider the Earth alive. You could even consider humans analogous to neurons with the potential to become reproductive organs (i.e. terraform Mars). The universe? - i guess, but we're getting into the territory of such broad definitions as to be meaningless.

Indeed, but we could go with humans analogous to a virus, I never did understand how a virus is not alive.

Why a virus? The problem is with the definition of life: any definition, not just the popular one. For any rigid definition of a complex system there are always going to be grey areas. It's like trying to draw the Mandelbrot set using a simpler curve, you'll have to cut off parts of the set. Unless the definition is so broad to include everything, but then why even bother trying to define it.

MigL Posted February 20, 2020 Posted February 20, 2020 By any definition, something that is alive, must Feed Expel waste Reproduce None of those criteria are met by the closed system that is planet Earth. The metaphysical is not scientific.

Reproduce, Well that is a struggle for a Planet... Well, two out of three ain't bad... 🙃
Bufofrog Posted February 20, 2020 Posted February 20, 2020 Planets aren't alive. Gee, how profound! I'll bet my coffee cup isn't alive either!
MigL Posted February 20, 2020 Posted February 20, 2020 So Dim... You listen to Meatloaf when you're stoned ? ( this is becoming a running joke )

dimreepr Posted February 21, 2020 Author Posted February 21, 2020 (edited) It doesn't matter if the planet is alive or not, that's not the point of the thread, much like my virus analogy, it's not about intent; but we can all turn vegan, plants ARE alive and they can grow back. Defining the Planet as 'not alive' doesn't mean it's dead, well not yet... Edited February 21, 2020 by dimreepr
MigL Posted February 21, 2020 Posted February 21, 2020 I think we all know what you mean and the point you're trying to convey. However, it becomes that much harder to correct new members using non-standard terminology when one of our more senior/respected members modifies accepted scientific terminology to bolster a point. ( next thing you know, some new age fanatic will come along and say the Earth has feelings... )

Fair point, maybe I should've placed this thread in philosophy. 17 minutes ago, MigL said: ( next thing you know, some new age fanatic will come along and say the Earth has feelings... ) That would be terrible, the vegans might get the wrong end of the stick and think a cabbage can suffer...

There are also more specific ones, but feeding usually refers to heterotrophic metabolism, which excludes autotrophs.

I am looking for a definition that tells me a volcano is definitely not alive since volcanoes seem to me to satisfy both MigL's list plus your growth one as well as the ability to exist in a dormant phase where none of these happen.

A virus fulfills this, but then so does some bacteria.
