Our world, without people?

Driddle

First Post
I questioned where to put this thread, but I really think it has potential for various RPGing background or situations, so I'm hoping it can stay here...

Let's say that for some reason (we'll discuss that later), every person on the planet suddenly disappeared. Gone from the world. No more people, anywhere. ... Further, all dressings of society were left in place exactly as they are now, without first being tidied or deconstructed.

What would be left of those remnants left to nature after 1,000 years? After 10,000 years? After 100,000 years?

For example: Would houses still be standing if there were no one left to control fires caused by lightning storms? How much damage would trees cause to structures without anyone around to keep them pruned away? Would any of them still be secure from wild animals years and years from now?

Or what about transportation -- How long does it take for vegetation and weather to wear away an entire stretch of Interstate? What would become of our vehicles?

And wildlife? Hoo-boy ... Which species would take over the landscape without people to get in the way?

Give me your best guesses.

As for the RPG aspect, most of you here are creative enough to see the potential angles: pandemic wipes out population in the future, and spacefaring explorers come home years later; or bereft of a sentient race, the World itself mystically repopulates with gnomes, elves, etc. from some other plane of existence; or animals (anthro)evolve to take our place and inherit a bunch of "relics" of the past age. Could have been caused by war, disease, mass kidnappings, whatever.

I'm trying to "realistically" imagine what would be left.

I can answer two of those questions from personal obervation.

Depending on where you are at woodend structures will last form a couple of decades to several hunderd years.

Asphat road will last for a couple of decades before being covered over completely then last for several more before being completly destored. Concret roads on the other hand could last several hunderd years. Just think of the Rome roads that are still visible through out Europe.
 

Darned if there wasn't a thread just like this about a year ago. I'm unsure of key terms to search for, however, and I don't want to bog down the server with a monster query to find it.

My speculation is that the concrete structures would last longest; cities inside of 100 years would look close to the same, minus some of the taller buildings that fell due to lack of repair and maintenance. Suburban areas would be largely overgrown. I know what our house looks like if we don't do lawn care and maintenance in a couple months' time - all yards with live grass would be knee-high grasslands, and vines could cause massive structural damage within just a decade or two.

But even 10,000 years isn't enough to have any kind of massive mutation with animals going on - but by 10,000 years, I would say even the cities would be enormous piles of concrete sand. They would be literally buried by eroded material from other buildings - you would have a literally buried city, with some sewers still open and viable, but likely bone-dry, and some sections cut off due to collapse. Cities by a sea or lakeside could possibly be underwater in 10,000 years, as sea levels change.
 


It comes down to location and what world shaking events take place, Mega-earthquakes, volcanoes, gobal warming, ice age, the wobble of the earth, all are events that we do not see in our lifetime but we know take place. How many volcanoes and earthquakes would re-shape the land, there are some scary things just waiting to occur.
 

I'm not sure where the first thread fits in, being something about PC's starting off a campaign about joining an army. The second one was about the effects of erosion on a battlefield, which is closer, but I could swear there was a post sometime last year (early last year) that SPECIFICALLY asked about what would be left of man-made structures after 10,000 years.

Or it could be an elaborate case of deja vu. :) Thanks for the links though!

That's a possibility. Or it could be an elaborate case of deja vu. :)
