Human intervention refers to the actions taken by people to influence or alter natural processes or systems. This can include activities like agriculture, where farmers modify land and crops to increase food production, or conservation efforts aimed at protecting endangered species and their habitats. Such interventions can have both positive and negative effects on the environment. For example, while reforestation can help restore ecosystems, excessive urban development may lead to habitat destruction. Understanding the balance between human needs and environmental health is crucial for sustainable development.
