It is difficult to provide a comprehensive summary of what the Earth was like 100 years ago, as the conditions varied greatly from place to place and have also changed significantly over time. However, some general observations about the Earth 100 years ago include:
In 1922, the world population was about 1.9 billion, which is significantly lower than it is today.
Many parts of the world were still relatively rural and agriculturally based, with relatively limited industrialization and urbanization compared to the present day.
There were fewer automobiles and other forms of mechanized transportation, and many people still relied on horses and other animals for transportation.
Many people in developing countries still lived in extreme poverty, with limited access to education, healthcare, and other basic necessities.
Global communications and transportation networks were less developed than they are today, and it was more difficult to connect with people in other parts of the world.
Climate change was not a widely recognized issue, and greenhouse gas emissions were much lower than they are today.
There were fewer environmental protections in place, and pollution and environmental degradation were more common.
Overall, the Earth 100 years ago was a very different place than it is today, with many social, economic, and environmental differences.
