Here is an Associated Press story from Newsday about Apa's efforts:
Before Apa became a guide in 1985, his village was devastated by a flash flood from a mountain lake that burst its banks. He is now trying to help his countrymen prepare for such a possibility again, and to warn the world that changing environments are making the danger greater than ever. From the Associated Press:
The 51-year-old Apa, who like most Sherpas uses only one name, is trekking the length of Nepal to warn villagers to prepare themselves for change. A third of the way along his 120-day journey, he has already seen many lakes that look ready to spill.
"If it happens again, many villages would be washed away and lives lost," he said during a break in his trek in Tatopani, a resort village near the Tibet border.
Apa's 21 ascents of the world's highest mountain have given him a unique up-close view of conditions in the Himalayas. Read the full story here.
Thanks Apa Sherpa for going where few have gone, and for carrying your message across the world.
