Over the course of biking across North and South America, David gave over 150 presentations, speaking in English and Spanish, sharing stories of bicycle travel and describing what climate change means for the places he visited. Most of these presentations have focused on David's 21,000-mile journey across North and South America, and draw on the best of more than 15,000 photographs and videos taken during that time period.
Testimonials
"This is the kind of adventure we need more of-someone actually taking what they know and carrying it out to the people who need to hear it. Pedaling a bike, and peddling the truth about the most important issue of our time." Bill McKibben, author and environmentalist, 350.org
"Thank you, David, for this inspired presentation. Every part of your 21,000-mile journey came alive for our students. Your talk left us with
the sense that a life-changing, climate-saving adventure is within anyone's grasp, and sparked exciting conversations across the school about how to
begin." Carolyn Cooke, Pacific Community Charter High School, Anchor Bay, CA
"David came to my Senior Environmental Science Classes both before and after his Ride. He inspired my students by showing them the power of one--that individuals can make a difference in the world, and spread ideals of hope, education, and possibilities to change the devastating path we are on." Elizabeth Brimhall, Palo Alto High School, Palo Alto, CA
