Imagine a world where technology and nature have blended seamlessly. Create an artwork or story showcasing a city that has fully embraced green technologies and sustainable living. This city should feature vertical gardens, renewable energy sources like wind turbines and solar panels, and public transportation systems that produce zero emissions. Think of artists like Yoko Ono or Banksy who often incorporate strong messages into their work. How would they portray such a city? Would they focus on the harmony between nature and technology or highlight the struggles that led to this utopia?
