Selina Juul makes a strong case in this TEDx Talk that the future of a better world and thus of the planet depends on individuals not wasting food. In her presentation, Juul connects the sheer volume of food waste in Western society to consumerism and discusses food as a political tool that can help create lasting social change, lower greenhouse emissions, and feed those who suffer from food insecurity.  The Danish woman is responsible for launching an entire movement via Facebook when a page she started grew rapidly in four years to become Denmark’s leading NGO against food waste.
