I think all the non-famous car shows must be stopped. Things like F1 is ok because it generates a lot of money and supports countries. But all those little junk car races is just stupid and polute our atmosphere.

And then how will you get F1 drivers in a couple of years from now?
Yeah... there are a few issues with these factoids. A few of us deconstructed this the last time it was posted here. I don't presently have the motivation to do so again, but many of these are inaccurate, misconstrued and/or overststements.

You really should look them up for yourself though.
Yeah, I for one am sceptical of the increased gas mileage. Engine efficiency would increase yes, but you've also increased the air resistance by increasing the overall density of the air (~20% more oxygen). I think that right there would eliminate any increased efficiency in the engine.
But overall an entertaining post.
That's a good point I think was over looked last time.
I will add this though:
Our blue skies has nothing to do with oxygen. It's due to the Rayliegh scattering effect of nitrogen, not oxygen. Since the atmosphere is 78% nitrogen, the sky would appear unchanged.
No. It doesn't work like that. Oxygen is transparent to visible light.
There's only two things that will change the color of the sky:
1) The percentage of nitrogen.
2) The angle of the sunlight through that atmosphere. (The apparent depth the light has to travel.)
.
PS, the sky is actually more violet than blue, but the human eye lacks significant violet receptors, so we see it as blue.
Oxygen actually is a light blue color. If you would like too see, liquify it (or look up liquid oxygen).
.
That being said, smitty is otherwise correct (at least based on my knoledge)
Actually since oxygen helps to form radicals in our bodies it would probably shorten our lifespan. Not to mention kill off a bunch of bacteria. A little higher percentage (50%) oxygen is toxic and will cause acute respiratory distress which is when your lungs fill up with liquid and you drown. Yummy
Molecular oxygen in the air isn't what protects us from uv light...
Melanin in our skin and the earths magnetic core does. Oxygen provides no barrier agains UV rays.
I was gonna make a whole speach about how you are wrong but instead I'm going to paste a link which does it much beter than I ever could. http://en.m.wikipedia.org/wiki/Ozone_layer
needless to say, I unfriended her.
:O
