Habitat modification refers to the changes made to natural environments by human activities. This can include actions like deforestation, urban development, and agriculture, which alter the landscape and affect local ecosystems. These changes can lead to the loss of biodiversity, as many species may struggle to adapt to the new conditions. Additionally, habitat modification can impact the availability of resources such as food and shelter for wildlife. For example, when forests are cleared for farming or construction, animals may lose their homes and food sources, leading to population declines or even extinction for some species.
