On Sunday, March 5th, Dr. John Francis, environmental educator and National Geographic Explorer, will be giving a lecture at the Temple University, Ambler Campus.

From Temple Ambler:

Dr. Francis began his work in 1971 when, after witnessing an oil spill in San Francisco Bay, he stopped using motorized vehicles and took a vow of silence lasting 17 years.

The founder of Planetwalk, he is the author of Planetwalker: 17 Years of Silence, 22 Years of Walking, and Ragged Edge of Silence: Finding Peace in a Noisy World.

After the lecture, there will be a reception with refreshments. You must register and pay in advance to attend. Tickets can be purchased here.
