What was the environment like 100 years ago?

A century ago, around the 1920s, the environment was markedly different from today. Industrialization was rapidly expanding, leading to increased pollution in urban areas, while rural regions were often characterized by less intense human impact. Deforestation and habitat destruction were common as agriculture expanded, but awareness of environmental issues was minimal. Overall, the balance between nature and human activity was beginning to shift, setting the stage for future environmental challenges.
