What is the Ecological Importance of Coral Reefs?

On top of supporting marine biodiversity, coral reefs protect against coastal erosion, provide habitats and breeding spaces for marine species, and play an important role in nutrient cycling. Coral reefs are also critical for local communities that rely on the reefs for fishing and marine tourism.  

How to See the Best of East Africa’s Coral Reefs 

To really experience the best that East Africa’s coral reefs have to offer, you’ll want to go snorkeling or scuba diving. The region’s clear waters, abundant marine life, and bright and colorful coral gardens make for some of the best underwater experiences you can have.

Threats to East Africa’s coral reefs include overfishing, pollution, climate change, and increasing coastal development. Rising sea temperatures, ocean acidification, and severe storms that are becoming more frequent, all add up to have a terrible effect on the vulnerable underwater ecosystems.
