- [AI â when harnessed correctly â can strengthen democracy]( Lead story The U.S. has a lot of public land â about 28% of the nationâs surface area is owned by the federal government â and millions of Americans will use it during the summer months for hiking, camping, fishing and other outdoor activities. But you may find yourself fighting traffic at popular spots. Some national parks are so crowded that they now require reservations or timed entry passes. As Boise State University historian Emily Wakild points out, many other U.S. public lands, including national forests, grasslands, monuments and seashores, are also coming under strain from heavy use. âFinding solutions requires visitors, gateway communities, state agencies and the outdoor industry to collaborate,â Wakild writes. The goal is to make trails, lakes and other popular destinations on federal land accessible, [while also protecting these resources for others to enjoy](.
