The 113th Congress, spanning January 2013 to December 2014, may be remembered for its relative lack of productivity and growing polarization. In terms of general lawmaking, it appears this Congress enacted fewer laws, by a wide margin, than any other since at least 1947, the date to which the House clerk’s records go back.

The European Commission has suspended the import of horsemeat from Mexico to the European Union due to food safety concerns, and it’s a decision that has huge implications for the slaughter of American horses for human consumption.

In honor of the 60th anniversary of The Humane Society of the United States, LIFE Magazine has revisited the classic Stan Wayman photo-essay, “Concentration Camps for Dogs.” The eight-page article and series of shocking photos, originally published in February 1966, built on a five-year HSUS investigation of dog dealing that brought to light the mistreatment of pets stolen and sold to medical research.

The Department of Defense recently announced that it will halt the use of live animals in a variety of medical training programs, beginning January 1.

One of their constant refrains is that Question 1—which would ban the cruel and unsporting hounding, trapping, and baiting of bears in the last state to allow all three extreme methods—is largely funded by out-of-state groups, including The HSUS and HSLF.

Way out in the central Pacific, there’s a swath of ocean twice the size of Texas where millions of marine animals now have safe haven from commercial killing, entanglement in fishing lines, and other human-caused dangers.

In a late-night, nail-biting vote yesterday, the Missouri House of Representatives failed to override Gov. Jay Nixon’s veto of a bill that would’ve relaxed restrictions on captive deer farms. Language in the bill reclassified captive deer as “livestock” rather than “wildlife.” The Senate had voted to override the veto, and the House failed by just one vote to get the two-thirds majority needed.

This week marked a dark centennial in our relationship with animals. On September 1, 1914, the last known passenger pigeon, Martha, died alone in captivity at the Cincinnati Zoo.

It’s rare that we know the exact date a species became extinct, but in this case, we know it’s been 100 years since the extermination of passenger pigeons, which used to number in the billions in the United States.
