It was a sunny morning in Lisbon, and Sofia, now 30, woke up in her completely sustainable home. Since 2035, all residences have used exclusively renewable energy, and the neighborhood where she lived was surrounded by trees and vertical gardens. Before leaving for work, Sofia programmed her autonomous electric bike, which would take her to the city center in a few minutes.

As he crossed the streets, he observed how public air transport, implemented in 2040, had transformed urban mobility. Small electric aircraft connected major European cities, reducing travel to a few hours.

At work, Sofia was part of an international team that met in holo-space, a technology that designed 3D holograms of her colleagues scattered across different countries. It reflected how collaboration between countries was essential to combat climate change and eradicate inequality.

At night, while admiring the clear sky from his balcony, he thought about how, between 2025 and 2050, humanity finally learned to live in harmony with the planet.
