Or our technology would be able to handle it. As in procure enough food and space.

So you have colonies on Mars, Jupiter, Mercury, Pluto, and every other planet in this system, becuase there just isn't any more room on Earth. These planets obviously cannot support life, so rescources from earth, such as oxygen ,water, food, some form of fuels, and coffee, must be shiped there. You'll likly need metals from Earth to build colonies. So when Earth's rescources are depleted, we all die.

Medical science becomes more adept at replacing/transplanting parts. Stem cell technology may regenerate certain tissues, but living cells still have a Hayflick limit. Unless the entire organism is periodically replaced there is no corporeal immortality.

There is a multitude of scientific research in progress right now that aims to optimistically eliminate the decay caused by cellular aging (currently known to be caused by the shortening of DNA base sequences called telomers at the end of chromosomes – which leads to cellular senescence, which is the cause of the Hayflick limit). Thus, with the combination of medical science, stem cell usage and gene therapy, the age limit may yet be lifted without the need to perform complete overhauls of the human body.

So coffee’s no longer a food and deserves mention all of it’s own now, eh? There is nothing indicating that metals could not be mined from other planet in this solar system, or for that matter, asteroids or comets, and the ideal setup would be to establish mining operations on the other planets using a minimum of resources from Earth. Another idea, posed by the more imaginative of the field, suggests that the transmutation of elements (which HAS been accomplished using particle accelerators on elements heavier than Uranium, up to ununhexium, and are called transuranium elements) could be modified to produce lighter elements, such as oxygen and hydrogen (though who would need to artificially create hydrogen would have to be insane hydrogen consumers) from more abundant elements (most of the non-metals are widely available throughout the solar system and galaxy) mined off world. The Earth doesn’t have to be humanities resource tether in the future.

Hell yeah!

I did forget about the mining on other planets, but you will definitly need Earth metal to get started.
