What exactly is ecosphere?

[icakeov]

Hi I have been trying to narrow down what exactly the word ecosphere defines, I have found multiple results:

- "physiological atmosphere" where humans are able to breathe
http://www.dictionary.com/browse/ecosphere

- "biosphere" a.k.a. ecosphere:
https://en.wikipedia.org/wiki/Biosphere

- "a planetary closed ecological system"
https://en.wikipedia.org/wiki/Ecosphere_(planetary)

I personally like the last one but would be nice if the word meant exclusively one thing.
Any thoughts or feedback appreciated.

Welcome to the real world!
To show what I mean: let's look at the word tip
I left the waiter a tip.
My doctor gave me a lifesaving health tip.
Kids used to tip me over as a joke.
Be careful, a small change in data can tip the result the other way.

Point: English words vary by context. One word, tip, has different meanings: Money left on a table, useful advice, push off balance, a change in standings or stance.
Also a lot of words for new scientific results are coined by media types. Sometimes they do not talk to one another when they do this, and we, the long suffering readers, get word salad. (PF term for senseless blather, and chopped up edible greens as well!)

:) Point taken. Thanks Jim.
It was really throwing me off and then I started realizing it didn't mean the one thing I thought it meant.

and for fun, another variation you may not use in your country

I took a load of rubbish to the tip ( rubbish dump, refuse collection point)

Tip has done well for itself. From where I grew up, “gore gore gore gore” means “up there hills burn worse”.
