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're undoubtedly used to it, but roads are extremely loud, as are planes that fly in the sky over our heads.

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

00:25as 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 for them, you name it.

00:38And there would be more life in general, including new trees, sprouted from seeds that fall where they may,

00:43with no people to keep grounds curated.

00:45And creatures like mice, raccoons, and other small mammals would start coming out of the woodwork

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

00:52Eventually, after around a decade, according to Basmajian,

00:55roads, bridges, and other massive man-made infrastructure would crumble and fall to pieces.

00:59A notion which reveals that our way of life isn't entirely natural,

01:03and to continue on in the way we do, requires constant upkeep.

01:07a McC apologizing for many more reasons.

01:11Have a good day for you, May 2020.
