SALT LAKE CITY -- Two Salt Lake City residents committed to telling the public about dangers of global warming are walking 350 miles.
Ryan and Jamie Pleune say their "Pilgrimage for Hope" calls attention to the number 350. It represents 350 parts per million -- the level of carbon dioxide beyond which global warming will become intolerable.
The Pleunes say our current carbon dioxide level measures in at 392 parts per million, and in an effort to bring it back down to 350, they are taking personal action.
"One of the things about climate change is it's just this hopeless thing. We don't see action on the political realm. It's very hard to believe that individual actions will do something," Jamie said.
Over the next few days, the couple will complete the last 19 miles of their 350 mile walk. Tuesday they visited the site of last summer's Chevron oil leak.
