00:00What would the world be like if every human suddenly disappeared?

00:07Well, Carlton Basmajian, professor and researcher of urban sprawl, writes for The Conversation,

00:11if that happened, the first thing you would notice would likely be the quietude.

00:15We are undoubtedly used to it, but roads are extremely loud, as are planes that fly in

00:20the sky over our heads.

00:21After a while, once you've gotten used to the silence, you might start to notice the

00:24cleaner air, as all of humankind's polluting power plants and vehicles have stopped operating.

00:29However, a big part of a world without people would include lots more bugs.

00:33That's because humans are tenacious in their pest control, removing insect habitats, spraying

00:37for them, you name it, and there would be more life in general, including new trees

00:41sprouted from seeds that fall where they may, with no people to keep grounds curated.

00:46And creatures like mice, raccoons, and other small mammals would start coming out of the

00:49woodwork to take over new habitats once cordoned off for people.

00:52Eventually, after around a decade, according to Basmajian, roads, bridges, and other massive

00:56man-made infrastructure would crumble and fall to pieces, a notion which reveals that

01:00our way of life isn't entirely natural, and to continue on in the way we do, requires

01:05constant upkeep.
