Nature Deficit Disorder Are you, or your children, deficient in vitamin “N” for nature? Updated On Feb 2, 2021 Published On February 1, 2021 Written By Leah Payne Are you, or your children, deficient in vitamin “N” for nature? The US-based non-governmental organization Children & Nature Network’s vision is “a world in which children have access to the benefits of nature everywhere they live, learn and play.” Its co-founder Richard Louv introduced the term “Nature-Deficit Disorder” in 2005 with the publication of his book, Last Child in the Woods: Saving Our Children from Nature-Deficit Disorder (Algonquin Books). As Laura Mylan, senior vice-president, Children & Nature Network, explains, “Nature-deficit disorder was not intended to be a medical diagnosis, but physicians, educators, parents, and caregivers recognized its profound impact on children.”
