Don't you think "OXYGEN" is killing us very slowly? Taking 20 to 70 years approximately? Or sometimes less than that for some.

It’s a funny idea, but oxygen isn’t slowly killing us. Oxygen is essential for life because our cells use it to produce energy through Cellular Respiration. While it can create small amounts of cell damage over time through Oxidative Stress, our bodies constantly repair this. So, oxygen isn’t the enemy, it’s what keeps us alive in the first place. 😀

@samueltyler2 Enlighten?

@Sutten it is really very complex, but whatever causes the stress, it isn't molecular oxygen. Stressors cause the release of what are known as "free radicals," which can affect cell function or integrity. Cellular metabolism involves chemical reactions, those do not even involve molecular oxygen.

In fact oxygen is toxic! When photosynthesis began on Earth (about 3 billion years ago), and the synthesis of molecular oxygen started, it almost killed the entire biosphere.
It's called the "Great Oxidation Event (GOE)". The sudden rise of free oxygen wiped out the vast majority of existing organisms. It's often called the "Oxygen Catastrophe".

@bluemachine Overall, I don't think the oxygen and carbon cycles normally produce anything new.
Well, they can't of course produce elements beyond reducing compounds to their separate elements, but the overall ratios do not change very much.

@bluemachine In almost 50 years of medical practice, over 30 of them as a clinical toxicologist, I never once even heard of anyone dying from oxygen, unless it was actually injected into a vein in high doses. There can be side effects of high concentration oxygen, but very unlikely to ever cause death. The death would be more likely due to the underlying illness for which oxygen was being used.

@samueltyler2 Oxygen for breathing air, yes, but it is surprising that the engines can find enough from that very thin air for combustion.

I think the Oxygen is polluted with pollution that is what is slowly killing the population of each Country. The best we can do is stay indoors as much as possible but our inside houses and homes could be just as bad as the outdoors?

@DancesWithWolves pollution is bad both in and outdoors.

no i don't think that.. God just limited our lifespan because he was sick of our nonsense .. people used to live over 900 years.. that's why pre flood dino's were so big too they are reptiles they grow as long as they live. there used to be a water barrier protecting us from the sun and its radiation but it broke during the flood.. before the flood there was no rain just earth mist

Nope. I remember the stories the older generation used to tell, about how when the world was full of trees and rainforests, the average life span for a human was a 160... Which I always thought they were smoking something they shouldn't have been.
Then there was a David Attenborough documentary about the time of Trees being everywhere long before humans. Where the insects were 5 times bigger due to all the extra oxygen. (Fuck that, I live in Australia, their big enough already) But also kinda gives credit to what the old fellas were saying.

@Thevy29 That mixes three different topics!
The world was far more afforested, yes, before humans started cutting down huge swathes of woodland; but historically it is only recently that the average human life span exceeded even seventy, let alone a hundred.
There is no evidence at all for humans having ever lived to over 150, so I wonder how some of the "older generation" thought they had.
Certainn geological eras hosted some, but by no means all, insect species much larger than their modern equivalents; but many tens, even a few hundred, millions of years before the proto-hominids even started to appear.

Of course not. Who invented such a silly question?
We cannot live without the oxygen in the atmosphere.
