when we ran out of fruits in the jungle, we moved to savana and beyond
when we ran out of animals to hunt we started to herd animals ourselves and started to grow plants
when we run out of land to grow plants and raise cattle, we will do vertical farming or make synthetic food
when we run out of metal to build skyscraper farms out of, we'll disassemble the moon and asteroids
when we run out of material in the entirety of Solar system and the sun burns out, we'll just move to another
