In 2015, Travis Rieder, a medical bioethicist with Johns Hopkins University's Berman Institute of Bioethics, was involved in a motorcycle accident that crushed his left foot.

Heading into the highlands of Tasmania, some 250 miles south of the Australian mainland, narrow black-topped roads meander through a wide river valley bounded by distant mountain bluffs. Two-track paths splinter off into grassy pastures, past skeletal trees bleached by sun and drought. All along the way, small signs dangle from wire fence lines: Danger Prohibited Area Poison.
