"You're probably wondering what happened before you got here. An awful lot of stuff, actually. Once we evolved into humans, things got pretty interesting. We figured out how to grow food and domesticate animals so we didn't have to spend all of our time hunting. Our tribes got much bigger, and we spread across the entire planet like an unstoppable virus. Then, after fighting a bunch of wars with each other over land, resources, and our made-up gods, we eventually got all of our tribes organized into a 'global civilization'. But, honestly, it wasn't at all organized, or civilized, and we continued to fight a lot of wars with each other. But we also figured out how to do science, which helped us develop technology. For a bunch of hairless apes, we've actually managed to invent some pretty incredible things. Computers, Medicines. Lasers. Microwave ovens. Artificial hearts. Atomic bombs. We even sent a few guys to the moon and brought them back. We also created a global communication network that let us talk to each other, all around the world, all the time. Pretty impressive, right?

"But that's where the bad news comes in. Our global civilization came at a huge cost. We needed a whole bunch of energy to build it, and we got that energy by burning fossil fuels, which came from dead plants and animals buried deep in the ground. We used up most of this fuel before you got here, and now it's pretty much all gone. This means that we no longer have enough energy to keep our civilization running like it was before. So we've had to cut back. Big-time. We call this the Global Energy Crisis, and it's been going on for a while now.

"Also, it turns out that burning all of those fossil fuels had some nasty side effects, like raising the temperature of our planet and screwing up the environment. So now the polar ice caps are melting, sea levels are rising, and the weather is all messed up. Plants and animals are dying off in record numbers, and lots of people are starving and homeless. And we're still fighting with each other, mostly over the few resources we have left.
