What are the two main changes human settlement made?

1. Alteration of the natural landscape: Human settlements often involve clearing land, cutting down trees, and building structures, which can significantly alter the natural landscape. This can lead to habitat destruction, loss of biodiversity, and changes in local ecosystems.

2. Infrastructure development: Human settlements require infrastructure such as roads, buildings, and utilities to support the population. This can lead to increased resource consumption, pollution, and changes in the local environment. Additionally, infrastructure development can also impact natural waterways, disrupt natural drainage patterns, and contribute to urban heat island effects.

1. Agriculture: The transition from hunting and gathering to farming allowed humans to establish permanent settlements and produce their own food. This led to a population explosion and the development of complex societies.
2. Urbanization: The concentration of people in cities allowed for the development of new technologies, trade networks, and forms of government. Cities became centers of innovation and power, and they played a key role in the development of human civilization.
