Question

The world is facing the accelerated rate of species extinctions due to human activities. Explain any three major causes of biodiversity losses.

Hint:

Tropical regions support a higher level of biodiversity due to stable environmental conditions and abundant resources, making them hotspots for various species. Ex situ conservation plays a critical role in preserving species that cannot be saved in the wild.

Answer 1

Three major causes of biodiversity losses:
1. Habitat destruction: Destruction of natural habitats, like deforestation and urbanization, leads to the loss of biodiversity by reducing the area available for species to live and reproduce.
2. Pollution: Pollution of air, water, and soil adversely affects many species, disrupting ecosystems and causing species to either migrate or go extinct.
3. Climate change: Global warming alters habitats and climate patterns, forcing species to adapt, migrate, or face extinction due to unsuitable environmental conditions.
