Scientists explore privilege and consequences of recreation for people and wildlife

The study found that uneven distribution of resources gives some individuals more access to play than others. Wildlife is a major draw for nature-based tourism, but human recreation has unintended consequences for biodiversity. To coexist with wildlife, it's essential to follow common-sense rules and minimize disturbance.
