Currently, in 2040, all available energy in the world is collected through renewable systems (photovoltaic, maritime, wind, geothermal) with low impact for humanity and having reduced C02 emissions to the point of absorbing carbon dioxide, pumping it into the earth and generating construction material (as they already do in a plant in Selfoss, Iceland). There are no wars in the world and humanity coexists to carry out the planet, barely consuming animal products, only milk or eggs, which everyone can obtain through their own production as pets or small-scale, local producers, who take care of these animals, without harming or overexploiting them and giving them a full and happy life, without sacrificing them to feed themselves. People are vegetarian or vegan and live happily with their animals. The working hours are much shorter (4 or 5 hours a day, from Monday to Thursday) and there is a base salary for everyone (who wants to earn an extra by working something else, it is optional). A happy and equal life for all. Countries and territories are self-sufficient and have a full and dignified life.
