Happy Earth Day! There's a lot of reason to worry about Mother Earth and our relationship with her, but I think its also important to inspire hope and celebrate success (as incomplete and limited as it might be) when it comes to our environmental plight. For that reason, I'm linking to my recent article for CityLab covering how Cape Town survived Day Zero last year. I have found inspiration in the progress Capetonians have made in reducing water consumption, and in how people can adapt behaviorally to reduce over-consumption. Lessons like this are important for us. Afterall, Earth will likely be around a lot longer than we will--we're the ones we need to save!
