Today I attended a "wild herb" tour, which I can confidently say was the closest I've ever gotten to being a hunter gatherer. I joined Chris, our guide, to a park in Berlin where he explained in detail the vegetation in the area - very informative!
Check out all the photos here. It's a work of wonder to see how resilient plants are and how they survive and thrive. Maybe worth exploring how that resilience can be used in, say, building more resilient software or machines.
