Instruction: Imagine you are the last person on Earth. Write a diary entry describing your thoughts and feelings.

Response: Dear Diary,
As warned a few days back, all the humans on planet Earth have disappeared. I am now the last person on Earth. There are a lot of positives and, at the same time, many negatives. I now have the freedom to do what I want without anyone being my obstacle. I can live my life according to my wish and do not have to follow the rules and restrictions of society. I can now live the “Hakuna Matata” life without worrying about my future temporarily. Alas! There’s also a negative side to this heaven on Earth. Now that the world's farmers have disappeared, the biodegradable food items would only last for a few days and would start to degrade if not refrigerated. All that would be left would be the canned and packed food items though these foodstuffs would also expire after a few years and eventually start to decompose. Soon the loneliness would also set into the brain. The reason was that man had evolved into a communal organism. Humans are born into an interdependent society where everyone is interdependent in their needs and wants. Without a community, the human race would probably perish. Soon, with no edible food remaining, I may also have to go out hunting for my meals like the early hunter-gatherers or to farm on the farmlands for three meals a day and would also forget about the worldly wants that the human society had created like electronic devices, automobiles, etc.
These devices would be of no use any more as a few months to go, the power reserves would run out of energy, and there would be no energy left to put them to good use.
Finally, I would miss my loved ones, friends, family, etc.
The memories, as I predict, may start to haunt me, and they may also begin to give me nightmares.
Memories would eventually turn to sadness, transforming into depression, but I would learn to live with it. Except for these changes, I don't think any other change will take place in my life.
With this, I end it here.
Yours,
(Name)
