Architects Danny Mui and Benjamin Sahagun have come up with a novel concept: buildings that scrub CO2 emissions from the air.
Perhaps you’re vaguely aware that the world is wracked by drinking water shortages. But as much as we hear that news these days, the problem always seems fairly abstract. Here’s an infographic that tries to solve that dilemma, by showing exactly why water supplies are falling in the world’s biggest cities.
Kräutli’s infographic has two basic components. One is a bubble chart that shows water price increases in cities across the world. Once you click the individual cities, you get a newsfeed filled with relevant news reports, and you also see the exact price of water, how it’s risen in the last five years, and how that compares to population growth.
As you can see, the stats are almost hard to believe. For example, Chicago has seen a 54% rise in water costs, compared to a 2% rise in population. And Chicago is hardly unusual. Washington, D.C. has seen a 44% rise; New York, 46%. And all while population has remained basically flat. (In Honduras, one town has seen water use grow by 1,617%.) Those rising costs reflect both diminishing water supplies and an aging infrastructure stretched by overuse.
