Editor's note
|
We’re running out of one of the world’s most important resources, so valuable that nations fight over it. But it’s not oil – it’s sand, and we need it for construction, industry, energy production and other uses. With shortages looming and sand mining causing serious environmental harm, some scholars are calling for international rules to manage the use of sand.
Have a hard time getting up this morning? Try spending more time with your friends and family, suggests Royette Tavernier of Wesleyan University. Some studies show that we sleep better when our waking hours are filled with rewarding social activities.
Tonight, the Conversation begins a new partnership with the PBS show “Third Rail with OZY.” Tune in to your local station to hear Malcolm Gladwell, Roxane Gay and Seth Weathers tackle the question: Is truth overrated? Not sure if it is or isn’t? Get better informed with these stories from our archive.
