When writer and outdoorsman Mike Lanza realized climate change was staking a full-scale assault on our most beloved national parks, he didn't just lament about how his kids wouldn't get to experience them the way he did. Instead, he saddled up his entire family -- wife Penny, son Nate, 10, and daughter Alex, 7 -- with packs, kayaks, and climbing gear and embarked on a year-long mission to visit them all. His new book Before They're Gone: A Family's Year-Long Quest to explore America's Most Endangered National Parks chronicles the adventure. He took some time to answer a few questions about our changing parks, life-list trip planning, and educating the next generation about climate change through adventures in the great outdoors.
