Overpriced medication is mostly limited to the US and a few other nations. Most of Europe has nationalized healthcare and cost up to 5 times lower.
I really mean it when I said we don't have enough energy. Total weight of humanity is about 400 million tons. So say, even if we launch only 1%; we still have to move 4 million tons up there. Let's take Mars, as that is the closest location. Optimal situation has 20.2 km/s delta v change. With a standard rocket engine, that'd amount in a 141 kg fuel to 1 kg payload need. So even with a space elevator, you'd use most of humanities remaining fossil fuel reserves.
You serious? Agriculture had a spike for sure. It's a direct famine vs hunger. I saw a graph intimes of Roman empire. It's was spectacular and definitive. Now you say that was sociological? All that grain? Seriously? Why it was such big of a deal with grain from Egypt? I lost you here It's was biggest popraise in the human history
Major miscommunication here. Today's drop off is sociological, all the others were not. It was simply a matter of abundant food reducing deaths, increasing growth, untill the empire collapsed and population lowered.
Also, pretty sure the biggest population raise was during the Industrial Revolution. We went from 1 billion to 6 over a small 2 centuries.
