Lately I came across this incredible project from writer Paul Salopek called the Out of Eden Walk. From 2013 to 2020 he is retracing on foot the migration of the first human beings from Ethiopia to Chile. Along the way he is engaging with issues such as climate change, mass migration and cultural survival. Check out the website here and there is also a crowdfunding campaign where you can help support the next leg of the journey here.
