Man-made causes include agricultural expansion, urbanization, logging, and infrastructure development.
Cutting down trees disturbs the ecological balance and reduces biodiversity.

Consequences of Deforestation

Increases atmospheric carbon dioxide levels, leading to global warming.
Reduces groundwater levels and affects rainfall patterns.
Disturbance in natural habitats leads to endangerment and extinction of various species.

Importance of National Parks and Wildlife Sanctuaries

Serve to protect biodiversity and keep ecosystems intact.
Enforce strict regulations against poaching, hunting, and habitat destruction.
Function as safe havens for both large and small endangered species.

Endangered Species and Extinction

Animals are categorized as endangered when their population decline poses extinction risks.
Smaller animals, such as reptiles and amphibians, may be more threatened than large mammals.
Extinction of species disrupts food chains and negatively affects ecosystem health.
