The greater Kilimanjaro region is one of the most threatened ecosystems on earth. As the snows, glaciers and rains retreat, millions of lives and the future of nations hang in the balance. A new report by the United Nations Environment Programme says that protecting East Africa’s mountain ecosystems would safeguard the region’s $7 billion tourism industry, not to mention the lives of millions of people and iconic endangered species.

“Across the continent, the damage done to these ecosystems is depriving people of the basic building blocks of life,” said Erik Solheim, head of UN Environment agency.

He said Mt. Kilimanjaro was an example of how climate change was severely damaging Africa’s mountains and the people who depend on them. Mount Kilimanjaro, the highest in Africa, contributes to more than a third of Tanzania’s revenue from tourism but is facing several problems, ranging from shrinking glacier to rampant wild fires. As climate change intensifies, it is essential that governments act swiftly to prevent more harm and more downward momentum. The report urges Tanzania to protect the mountain’s water catchment area by reforestation, investing in early warning systems and making climate adaptation a top priority.
