Five Ways to Make the Outdoors More Inclusive
Discover ways to help make our outdoor spaces, state and national parks more inclusive with these five ideas and action steps from outdoors experts and activists. According to the most recent National Parks Service survey, about more than 70 percent of those who visit or work in federal parks are white. Moreover, the outdoors industry workforce lacks representation from African Americans, the Latinx community, women, and members of the LGBTQ community, lending to low perceptions and limited access to the outdoors for minority populations. Consider discussing diversity in the outdoors with your middle and high school students and ways to make changes using these five ideas.
