Service Description

On Earth Day, April 22, 2002, our network of community leaders from across the world led a global wave of Deep Time Walk’s, bringing a deep time aspect to the ecological and climate emergency. Continuing to offer this experience to groups by reservation. Participants who join one of these walks will be able to: > Comprehend the vastness of Earth’s 4.6 billion year history by walking across a 4.6 km geological timeline of Earth (every step is one thousand years!), experiencing how humans have evolved in the blink of a geological eye. > Gain a sense of the high-level, macro-evolutionary story of Earth, learning about the coevolution of life with the environment and understand the story of our human family as deeply entangled with that of the Earth. > Understand that the Earth is not a static, passive backdrop on which humans reside, but a set of complex interrelated active actors which have in themselves agency to move and dramatically change the Earth’s systems. > Help participants overcome a widespread ‘temporal illiteracy’ and develop an appreciation of the long arc of deep time, helping people develop a sense of what Marcia Bjornerud calls ‘timefulness’. > Understand through the latest peer reviewed science the impact that humans are having on the Earth, initiating the sixth mass extinction. > Appreciate the gifts from deep time fostering people to become what Jonas Salk calls ‘good ancestors’, to consider their decisions based on long-term, intergenerational justice. > Obtain a transformative, deep experience that leads people into a profound connection and love of their local place. > Provide a rich set of hope-filled narratives for humanity, to inspire people to take urgent personal action and collective advocacy to address the climate and ecological emergency. Reservation is Required. $22 per participant or rates by group negotiable. 10% will go back to the Deep Time Walk initiative to support this work. This walk is 2.85 miles and will be at a conversational pace. Some of the scientific statistics shared will be at higher education levels, so may not be suitable for younger children, or at least don't expect them to comprehend all that is covered. Sheri's modifies the lesson to those attending. Deep Time Walk is the creation of Stephan Harding and Sergio Maraschin, of Schumacher College and the Deep Time Walk Project.
