C65iqOSCZOY 0:07–1:18 — Turn on a faucet and clean water rushes out, as much as we want, anytime we want.
C65iqOSCZOY 1:21–2:31 — There are perceptions that it is there in bountiful amounts and everyone has access to it because you can turn a tap, and that's a big problem.
C65iqOSCZOY 2:33–3:38 — We have 326 million trillion gallons of it. Water may freeze into ice or evaporate into air, but it doesn't leave our planet.
C65iqOSCZOY 3:42–4:43 — Hundreds of years ago, when the Aztecs settled on what is now Mexico City, they saw a giant lake. These are the last remnants of the canals they made.
C65iqOSCZOY 4:45–5:49 — We've gotten a lot better at accessing groundwater.
C65iqOSCZOY 5:51–6:53 — Climate change is making available water much more erratic. We're seeing areas around the world that are experiencing much more extended dry periods.
QaIOfgz8FVY 0:01–1:03 — At first, this looks like a perfectly normal map of New York City. You zoom in and there’s Broadway, and Bowery. But then you realize that the map is...wrong.
QaIOfgz8FVY 1:08–2:12 — His intentions reflected American ideas and his Quakerism. The lines on his grid weren’t just right angles, they were morally right angles.
QaIOfgz8FVY 2:14–3:20 — What little order that had developed was largely private and subject to frequent change. This 1776 map shows a planned grid with a large square.
QaIOfgz8FVY 3:28–4:29 — In 1807, the state established a new commission to create a workable plan, and it was huge.

字幕依据：We have 326 million trillion gallons of it. Water may freeze into ice or evaporate into air, but it doesn't leave our planet. If you sucked up all the water on Earth, it would fit into this sphere. But 97% of it is salty and 2% is trapped in ice at the poles, so all of humankind relies on just 1% of that water to survive. C65iqOSCZOY@2:33
字幕依据：Hundreds of years ago, when the Aztecs settled on what is now Mexico City, they saw a giant lake. These are the last remnants of the canals they made. When the Spanish came in the 16th century, one soldier marveled at the Aztec city rising from the water that seemed like an enchanted vision. C65iqOSCZOY@3:42
字幕依据：We've gotten a lot better at accessing groundwater. Those water deposits, called aquifers, have accumulated over millennia and they'll take millennia to fill back up. Groundwater is sort of like the savings account, which it's fine to draw on sometimes, especially when you have a drought. C65iqOSCZOY@4:45
字幕依据：Climate change is making available water much more erratic. We're seeing areas around the world that are experiencing much more extended dry periods. But the problem isn't just that there's more people on Earth using water, it's how we're using water. C65iqOSCZOY@5:51
字幕依据：At first, this looks like a perfectly normal map of New York City. You zoom in and there’s Broadway, and Bowery. But then you realize that the map is...wrong. Streets run diagonally and the map adds land beyond the edge of the island. QaIOfgz8FVY@0:01
字幕依据：What little order that had developed was largely private and subject to frequent change. This 1776 map shows a planned grid with a large square. That square belonged to the Delancey estate (Delaney was a typo). Because the prominent New York family supported the British during the Revolutionary War, the city confiscated their land after the war. QaIOfgz8FVY@2:14
字幕依据：In 1807, the state established a new commission to create a workable plan, and it was huge. In this map, this color shows the settled land, and this color shows the projected areas for the grid. In their official report, they said they’d planned for “a greater population than is collected at any spot on this side of China.” The grid made sense to hold it. QaIOfgz8FVY@3:28
字幕依据：“Edison was walking around calling Harvey Firestone dude.” Uh yeah, he was, and also one thing I wasn’t able to mention was that Edison was really hard of hearing at this time of his life, so basically every time you wanted to talk to him you had to yell directly in his ear. QaIOfgz8FVY@5:40
