Nepal continues to mourn the thousands who died after a massive earthquake. A global relief effort is now underway to assist more than a million people in need food assistance and other forms of relief.

Seismologist Brian Tucker says we need to do more than help the victims of natural disasters; we need to prepare vulnerable communities before disaster strikes.

The Center for Effective Philanthropy's Phil Buchanan says nonprofits should push back when the business world says it has the answers to our big social problems.

“Folks sometimes forget that philanthropy is addressing the very problems that have defied market solutions or in some cases are the result of market failure," says Phil Buchanan, President of the Center for Effective Philanthropy. But sometimes that is overlooked or underestimated by the start-up world, according to Buchanan. “There's way too much ignorance about the sector," Buchanan tells us. "Particularly given what an important role it has played in this country, and the fact that our nonprofit sector, with all its flaws and all its faults, and all the ways it could be better, is the envy of the world."

A small percentage of the second-hand clothes we donate to charity actually end up on the store shelves of our local Salvation Army or Goodwill, according to our guest Andrew Brooks. Eventually the clothes end up in the hands of for-profit companies, which sell our old t-shirts and jeans to poor people halfway across the globe. Brooks' new book, Clothing Poverty - The Hidden World of Fast Fashion and Second-hand Clothes, describes a multi-billion dollar industry rife with complications and even deceit.
