So, how many mushrooms is my life worth ?

Heard a "new" word recently - Fungible. How fungible is human life? To what extent can human life serve as a fungible currency? I quote Prof Peter Redfield "The question is far from abstract, as measures of life play an increasingly central role in int'l moral discourse 'n' justification for ....actions. Key metrics in global health like DALY, rest on assumed equivalences. NGO fundraising brochures, along with extensions of consequentialist ethics, suggest easy conversions between money and lives."
