Olga Murray, who lives in California, wanted to keep poor Nepalese families from selling their daughters into slavery. So she's offering them pigs instead. Murray founded a non-profit called The Nepalese Youth Opportunity Foundation, which gives piglets — which, grown, fetch the same $35-75 buyers would pay for a girl — in exchange for promises the girls will be sent to school. Already, this switcheroo has saved 3,000 girls. [San Francisco Chronicle, via Newser. Related: NYOF]
