Tippets: Lime Doser Machine, Bighead Carp in Minnesota, Urban Assembly New York Harbor School

  • Ever wonder what a “lime doser machine” (the kind they use to de-acidify mountain streams destroyed by mining waste) looks like? West Virginia just installed three of them at the headwaters of Three Fork Creek.
  • Minnesota officials think 27-pound carp caught on the St. Croix river may prove the invasive fish are “knocking on our door.”
  • The Wall Street Journal‘s coverage of the Urban Assembly New York Harbor School had us wondering whether we had stumbled through the back door of an exclusive yacht club (we had), but what a great idea: a school that teaches “the skills and ethics of stewardship.”
