The world in 100 years will be a very different place. With the advances in technology, many workstations would be replaced by robots, making manual labor obsolete. There would also be new and faster means of transportation, such as flying cars, allowing people to travel faster and farther than ever before. The climate would continue to increase in temperature, leading to extreme weather events and a decrease in the amount of arable land available for agriculture.

The world population would increase by several billion, leading to a decrease in the amount of available land for forests and fields. This would lead to more cities being built, with more people living in them. This would also lead to an increase in air pollution, as well as an increase in the amount of waste being produced. To combat this, new technologies would be developed to reduce the amount of pollution and waste produced.

In terms of energy, the world would be powered by renewable sources such as solar, wind, and geothermal. This would reduce the amount of pollution produced by traditional sources of energy, such as coal and oil. Nuclear energy would also be used in some areas, but with more safety measures in place to prevent accidents.

The world would also be more connected than ever before. With the advances in communication technology, people would be able to connect with each other from anywhere in the world. This would lead to a greater understanding of different cultures and customs, as well as an increase in global trade.

In terms of healthcare, the world would be a much healthier place. Advances in medical technology would lead to longer life expectancies and a decrease in the number of diseases. New treatments and cures would be developed to combat the most common diseases, such as cancer and heart disease.

The world in 100 years would be a very different place. With the advances in technology, people would be able to travel faster and farther than ever before, while also being more connected than ever before. The world population would increase, leading to an increase in air pollution and waste production. However, with the advances in renewable energy sources and medical technology, the world would be a much healthier and more sustainable place.
