The habitat of the last wild mountain gorillas in Virunga National Park is increasingly being threatened by the mining of metals for the production of mobile phones. The recycling of raw materials from used mobile phones is therefore an important step to protect this valuable habitat. For this reason, the Frankfurt Zoological Society FZS Conservation Ambassadors initiated the “A mobile phone for the Gorilla” collection campaign in 2009. BARTHAUER supports the gorilla protection project with an in-house mobile phone collection campaign. Mining is often carried out in illegal mines and the Virunga National Park in the heart of Africa is a centre of biodiversity and a UNESCO World Heritage Site where roughly half of the last 880 mountain gorillas in the world live. The soaring demand for metals in recent years created many illegal mining sites, which are destroying the habitat of the gorillas.
