It is a disappointing thing to see new playgrounds developed in city spaces sit there empty each day, or to walk in the park and hear no laughter. What is missing here is not the children per se, but materials and environments that create challenge, imagination, and creativity that make children want to play outdoors. The absence of such play environments is not only influencing the quantity and quality of children’s play, but also affecting children’s health and well-being. As adults, we need to support children in learning to enjoy what free play in the outdoors has to offer. We need to inspire imaginations, creative minds, and capable bodies. To do this, we can look toward two simple things: nature and adventure.
