Importance of Islands
- Biodiversity Hotspots: Islands are home to many endemic species found nowhere else on Earth.
- Economic Development: Islands rely on industries such as tourism, fishing, and agriculture for economic growth.
- Cultural Heritage: Islands often have rich cultural traditions and histories that are preserved by local communities.
- Environmental Conservation: Islands face environmental challenges like sea level rise and habitat destruction, making conservation efforts crucial.
In conclusion, islands are diverse and important landforms that play a significant role in the global ecosystem and human societies.
