Maximum-security prison inmates in Oregon that spent an hour a day for a year  watching nature videos were involved in 26 percent fewer violent acts compared with fellow inmates, and reported feeling significantly calmer, less irritable and more empathetic. The University of Utah study, published in Frontiers in Ecology and the Environment, states, “An estimated 5.3 million Americans live or work in nature-deprived venues. Such removal from nature can result in an ‘extinction of experience’ that can further lead to disinterest or disaffection toward natural settings, or even biophobia (fear of the natural environment). People that infrequently or never spend time in nature will be deprived of the numerous physical and emotional benefits that contact with nature affords.”
