Positive Futurism is more than a subgenre of optimistic speculative fiction. It's a mindset of envisioning and creating a beautiful planet powered by sustainable energy, conscientious technologies, and human societies that are cooperative and peaceful.
In science fiction, Positive Futurism is known as Solarpunk. Solarpunk visionaries see everything from an open economy (think "open floorplan" for money) to solar panels and community gardens instead of fertilized lawns in suburbia.
How do you envision the future?
