people, no water, big problem.
Only the deepest deep ecologist, or an analytical philosopher cares if the sahara really is dry. the rest of us just care if we can get a drink.

So the amazon doesn't produce 20% of the oxygen?
Fish and aquatic animals cannot split oxygen from water (H2O) or other oxygen-containing compounds. Only green plants and some bacteria can do that through photosynthesis and similar processes. Virtually all the oxygen we breath is manufactured by green plants. A total of three-fourths of the earth’s oxygen supply is produced by phytoplankton in the oceans.

You can make water materialize with a sheet of plastic and a small pebbel. You can cut into cactus's for water.
Waters the last of our issues. We can build a big ole ditch right down America and get canadian waters to flow to mexico.



This is good news! Finally some good news! We will all fry to death, but at least we will literally be "breathing easy" until the bitter end

Did anyone here ever try that or was that just a scam? I would imagine it would be incredibly hard to determine if you actually bought anything. It does seem like the only way to save them however.

Is this post a joke???? The %oxygen in the atmosphere is not proportional to the rate of photosynthesis. It's a standing mass of gas which is slowly added to and subtracted from by photosynthesis and respiration/combustion. The turnover time is about 100,000 years. Killing the Amazon would be awful but would have no significant effect on %oxygen for millenia.

c8h18 + 12O2 = 8Co2 + 9 H20. when burning octane.
1 mole Octane takes 12 moles O2 (oxygen) to burn.

My grandparents say it has gotten a lot tougher to breath than when they were teenagers

syncline wrote:turmoil wrote:I don't mean to get into an envronmental debate....I just wanna know at what percentage is human life not possible. Right now oxygen is roughly 20% of the atmosphere, and the amazon provides roughly 20% of that. If the amazon goes to desert within a few years or gets completely cut down, can we survive on roughly 16% oxygen? 10%?

Dublin in the Rare Old Times
Raised on songs and stories, heroes of renown.
Are the passing tales and glories, that once was Dublin town.
The hallowed halls and houses, the haunting children's rhymes.
That once was Dublin city in the rare old times.
Ring a ring a Rosie, as the light declines,
I remember Dublin city in the rare old times
My name it is Sean Dempsey, as Dublin as can be
Born hard and late in Pimlico, in a house that ceased to be.
By trade I was a cooper, lost out to redundancy.
Like my house that fell to progress, my trade's a memory.
And I courted Peggy Dignan, as pretty as you please,
A rogue and child of Mary, from the rebel Liberties.
I lost her to a student chap, with skin as black as coal.
When he took her off to Birmingham, she took away my soul.
Ring a ring a Rosie, as the light declines,
I remember Dublin city in the rare old times
The years have made me bitter, tha gargle dims my brain,
'cause Dublin keeps on changing, and nothing seems the same.
The Pillar and the Met have gone,
the Royale long since pulled down,
As the great unyielding concrete, makes a city of my town.
Ring a ring a Rosie, as the light declines,
I remember Dublin city in the rare old times
Fare thee well sweet Anna Liffey,
I can no longer stay,
And watch the new glass cages, that spring up along the Quay.
My mind's too full of memories, too old to hear new chimes,
I'm part of what was Dublin, in the rare old times.
Ring a ring a Rosie, as the light declines,
I remember Dublin city in the rare old times
