Lake Bogoria in Kenya's Great Rift Valley is under threat, as climate change disrupts water levels and dilutes vital minerals. This is depleting the flamingos' food sources, forcing them into mass migration. According to the Lake Bogoria Game Reserve, the flamingo population has declined from 1.5 million to 300,000 in the last ten years. Michael Kimeli, an ornithologist, explains how this has impacted tourism in the area. | BBC News Africa

RIFT VALLEY FORMATION A rift valley is a large elongated depression in the Earth’s crust, bounded by parallel faults, that forms when the crust is pulled apart by tensional forces. This geological feature is a result of divergent plate boundaries where tectonic plates move away from each other, causing the crust to thin, crack, and sink. PROCESS OF FORMATION: 1. Initial Uplift – Mantle convection and heat buildup cause the lithosphere to bulge and stretch. 2. Crustal Fracturing – The brittle cru
