Step 1: Biodiversity hotspots are regions that are rich in species and have a high degree of endemism, meaning that these regions contain species that are not found anywhere else on Earth. At the same time, these areas face significant threats, such as habitat destruction and climate change.
Step 2: Two examples of biodiversity hotspots are: 1. The Western Ghats in India 2. The Amazon Rainforest in South America
Step 3: The Western Ghats are a mountain range along the western coast of India and are recognized for their rich diversity of plant and animal species. The Amazon Rainforest, known as the "lungs of the Earth," is a critical biodiversity hotspot that spans across multiple countries in South America.
