What "leave no trace" means as cuts hit national parks

What they're saying: Evelynn Escobar, the founder and executive director of Hike Clerb, a nonprofit that aims to increase diversity in natural spaces, said on Instagram that everyone needs to think "What would a ranger do?"

• "If you see trash on the ground, pick it up and put it in the trash. You see wildlife on the trail, keep a safe distance and don't interact with them. You see restoration areas marked 'in progress,' you're going to stay off those lands," Escobar said.

The bottom line: Mark Eller, a spokesperson for Leave No Trace — an educational nonprofit that promotes environmental stewardship — reiterated that message, and said he hopes people gain a renewed sense of personal responsibility.

• "The degree to which the public can equip themselves to be stewards of the parks is going to make a huge difference," he said.
