Invited review: The consumer and dairy food waste: An individual plus policy, systems, and environmental perspective.

An estimated 40% of food produced in the United States is wasted, which poses a significant barrier to achieving a sustainable future-so much so that the United Nations Sustainable Development Goal no. 12, to "ensure sustainable consumption and production patterns," includes a goal to "halve per capita global food waste at the retail and consumer level, and reduce food losses along the production and supply chains by 2030." Annually, consumers waste approximately 90 billion pounds of food, equating to roughly 1 pound per person per day.
