In the forested depths of eastern Congo lies Virunga National Park, one of the most bio-diverse places in the world and home to the last of the mountain gorillas. In this wild, but enchanted environment, a small and embattled team of park rangers - including an ex-child soldier turned ranger, a carer of orphan gorillas and a Belgian conservationist - protect this UNESCO world heritage site from armed militia, poachers and the dark forces struggling to control Congo's rich natural resources. When the newly formed M23 rebel group declares war in May 2012, a new conflict threatens the lives and stability of everyone and everything they've worked so hard to protect.
2014 • Environment
Something weird seems to be happening to our weather - it appears to be getting more extreme. In the past few years we have shivered through two record-breaking cold winters and parts of the country have experienced intense droughts and torrential floods. It is a pattern that appears to be playing out across the globe. Hurricane chasers are recording bigger storms and in Texas, record-breaking rain has been followed by record-breaking drought. Horizon follows the scientists who are trying to understand what's been happening to our weather and investigates if these extremes are a taste of what is to come.
