Grade 9 Biological Diversity Practice Exam 2026 – Full Prep Guide

Human intervention in native habitats is a significant threat to biodiversity because it often leads to habitat destruction and fragmentation, which can severely disrupt local ecosystems. When humans alter landscapes through urban development, agriculture, or industrial activities, many species lose their natural habitats. This loss can result in diminished populations, increased competition for resources, and can even lead to extinction for some species if they are unable to adapt to the new conditions.

While natural disasters, climate change, and species migrating to new areas also impact biodiversity, they tend to be factors that can occur naturally or as a consequence of broader environmental changes rather than being directly caused by human actions. Human intervention is particularly concerning because it is often irreversible and can introduce new challenges that native species are not equipped to handle. Thus, addressing human impacts on the environment is crucial for protecting and preserving biodiversity.
