Shareable contributor Rachel Botsman and co-author Roo Rogers just released a video previewing What's Mine is Yours: The Rise of Collaborative Consumption, their new book being released in September about sharing.
This year, we’ve seen Mutual Aid in Motion.
From scaling sharing hubs to Mutual Aid 101 trainings, we’re helping communities build the tools they need.
Every dollar fuels lasting resilience – proving that when we move together, we all move forward.
One thing I have in common with Rachel is that I've learned that sharing is much bigger than we had thought. In a recent example, I was quite surprised by the growth of bikesharing. According to the video, it's the fastest growing form of transportation. All the major cities in the US has a bikesharing program in development. Who knew?
In addition to quantifying the trend, the video lays out three major categories of sharing reflecting the book's organization:
- Product Service Systems like bikesharing and carsharing
- Redistribution Markets like Freecycle and eBay
- Collaborative Lifestyles like Couchsurfing, and Lending Club
This schema helps make sense of the space. But however you slice it, there's a whole lot of sharing going on. It's in the billions.
