Food for thought.

The Earths circumference at the equator is 40,075km.

The Airbus A380-800 can carry up to 853 people in its all economy class form, at 900kmh with a design range of 15,400 km. This means, assuming somewhere to land and fuel up where it needs to, an Airbus with 853 people on board can circle the world in 44.5hrs + 2 fuel stops.

Makes the Earth seem so much smaller doesn't it? We can go around it via commercial transport in less than 2 days, or could if anyone was offering that particular flight.

Even so, it's pretty huge compared to the water and air.

In the image below, the entire worlds water, (including oceans, lakes, rivers and humidity), is pictured on the left as a single huge ball of liquid.

On the right, the entire worlds atmosphere.. including the more than 90% of the atmosphere which is too thin to breathe.. is pictured as a single huge ball of gas.

The two things we need the most to survive. Suddenly they don't seem so plentiful.

This image shows in approximate scale the 100km band of atmosphere surrounding the earth.

Keep in mind that most people can breathe ok at 3.5km high, but aircraft safety rules don't allow unpressurised aircraft above 5km without oxygen masks being worn. Most modern passenger jets travel between 10-12km high, but they are pressurised. Some mountain climbers reach 8km, but umm those guys are pretty special and their training is incredible..

The Red Bull balloon jump the other week was from 39km high... and definitely no breathable air up there.

The air we need as a species (and of course all the other species need it too, and we need them..) to survive comprises only about the lower 10% of the narrow band pictured here..

Feeling a bit small and insignificant on this earth tonight are we??

Quick we better start killing each other off faster.....


Having an interest in astronomy

Its mind boggling how many things had to happen in just the right way/order for life to exist.

To highlight the smallness of humanity, let alone yourselves, look at this:

Negative.

Just means he is travelling at least 1669.79km/h.

Or ~1.36 times the speed of sound.

Or based on the speed of light of 1,079,252,850 km/h (300,000,000m/s), 0.00000154717 times the speed of light.

Don't hate.

Fair enough. We should be looking after our planet by keeping our resourses of air and water as clean as we can for future generations.
Without the water and air Earth would be just like Mars.
And on that tangent...thats all the air and water the Earth ever had...even when the dinosaurs roamed it. It can't go anywhere can it? Could we end up like Mars?

In theory, you could make water by smashing Hydrogen and Oxygen together, but it requires more than just stirring it together. They don't just mix like a scrambled eggs.

You need some form if energy or spark or something along those lines.

But then it's still not that easy. Oxygen supports combustion, and we all know what Hydrogen does when an ignition sure is introduced (Hindenburg, anyone?).

Until then we need to preserve the **** of what small amount of water we have.

As for air, just plant more trees? Idk. I'm far from a Biologist/Botanist.
