Which human-created aspect can significantly impact the environment, such as pollution or urban infrastructure?

Human-created aspects, described as human factors, encompass various activities like industrial production, urban development, and transportation infrastructures that directly influence the environment. For instance, industrial production can lead to air and water pollution, while urban infrastructure such as roads and buildings can alter landscapes, affect local ecosystems, and contribute to habitat loss. This understanding underscores the significant role human activities play in environmental changes, making human factors a key focus in geography and environmental studies.

Natural factors, in contrast, involve physical elements like climate and geology that can also affect the environment but are not created by human actions. Geographic factors typically relate to the spatial aspects and distribution of various elements in the environment, while social factors usually pertain to the ways communities interact, which can influence but do not directly create environmental conditions. Thus, the concept of human factors best captures the intent of how human activities shape environmental outcomes.
