The butterfly effect theory comes from meteorologist Edward Lorenz and the idea that the development of a tornado can be “influenced by minor perturbations such as the flapping of the wings of a distant butterfly several weeks earlier.” In other words, small fluctuations or changes can have a dramatic impact somewhere else at a later time. Even though it can feel like our individual actions will not make a big enough difference quickly enough, everything we do matters, and our collective efforts will have a significant positive impact in our communities and around the world.
