    The 22 trillion won Four Rivers Project’s 16 weirs slowed flows and caused algal blooms across South Korea’s rivers.
    Segment 1 — The Cold Open
    In June 2008, President Lee Myung-bak directed his land minister to add weirs and deepen dredging on the four major rivers rather than rely on dike reinforcement alone. The 22 trillion won project that followed created sixteen concrete structures meant to store water and reduce flood risk. ...

    Correction to episode 155: The episode said the Eastland rolled the opposite way when passengers moved back toward the center and came to rest in fifteen feet of water. She lurched to port, the way she was already listing, and rolled onto her port side in about twenty feet of water. The concrete was not poured in 1915 for the new davits: in 1914 the owners replaced the forward dining room's wooden floor with two inches of concrete and added more near the aft gangway, 15 to 20 tons in all.

    In 1972 Inco built a 381-metre stack to clear Sudbury's air, and sent the sulphur elsewhere instead.
    Segment 1 — The Cold Open
    In 1972 the Inco nickel smelter in Sudbury, Ontario, completed a chimney 381 metres tall, the tallest in the Western Hemisphere at the time. The structure was meant to lift sulphur dioxide high enough for the winds to carry it past the city. ...

    Correction to episode 152: The article described the callback gap in Agan and Starr's study as 7 and then 43 percentage points and said the move more than doubled the white applicants' relative advantage. The study's gaps are relative: white applicants were called back about 7 percent more often before the ban and about 43 percent more often after it, an advantage roughly six times as large. The audio did not carry this passage.

    Segment 1 — The Cold Open

    Correction to episode 151: The hook and cold open said India's vultures fell to one-thousandth of their earlier numbers. That figure is the white-rumped vulture's; the long-billed and slender-billed vultures fell by about 97 percent, as the episode said later. The claim that the decline began in 1994 when the diclofenac patent expired is flagged as unverified on the claims record.

    Diclofenac given to Indian cattle from 1994 cut vulture numbers by 97 percent or more and added over 100,000 human deaths yearly.
    Segment 1 — The Cold Open
    In 1994, after the patent on the painkiller diclofenac expired, Indian generic manufacturers began selling the drug at low cost for treating cattle. Within a decade the three Gyps vulture species that had once numbered in the tens of millions across the subcontinent fell by roughly 97 percent or more, the white-rumped vulture to about one-thousandth of its earlier abundance. ...

    India issued 80 million free gas connections since 2016, yet 90 percent of users still burned firewood.
    Segment 1 — The Cold Open
    On 1 May 2016 Prime Minister Narendra Modi stood in Ballia, Uttar Pradesh, and launched the Pradhan Mantri Ujjwala Yojana, promising free LPG connections to five crore poor households so women would no longer cook over wood and dung fires. By September 2019 the scheme had delivered more than eight crore connections. ...

    Correction to episode 149: This episode said Wisconsin's yearly savings from fewer deer-vehicle collisions, about $10.9 million, were roughly 63 times the livestock losses the state had paid out "over the preceding decades", after putting those payments at about $3 million over 35 years. The 2021 PNAS study compares one year with one year: the annual collision savings were about 63 times the state's annual compensation for verified wolf kills of livestock. The headline's "24 percent each year" is also wrong: collisions in counties wolves entered were about 24 percent lower, a drop in level, not a cut repeated every year.

About Unintended Consequences

From the publisher's feed

Every day, one true story of good intentions gone sideways.
