In 2040, I see the earth from my heaven. I'm glad I don't have to be in that reality as life on earth has evolved. all the wars that raged on earth have destroyed cities and the earth so it's not possible to recognize the nature and communities that existed in 2025. There are not so many people on earth because they are dead, either by war or starvation. But the earth remains and people try to build their lives based on the conditions that exist. They grow , trying to find seeds from plants that are edible and nourishing. There are some people who still have knowledge of medicinal plants and edible plants. The knowledge of how to prepare and treat the plants is also available.
There are not so many wild animals, you try to help the animals survive. The animals can provide food for the people, and also heat. The homes are cold and you have to burn to keep warm and cook. The water needs to be boiled and strained to be drinkable, there are only a few sources where fresh water is available to fetch.
cohesion between people and the different communities formed must be based on community and helping each other. The key to survival is to have cohesion and community. There are leaders who have a foundation to stand on that makes them good leaders, and who do not seek division, it is a prerequisite for the survival of man.
