The world’s oldest forests are facing growing pressure from all sides. Their decline isn’t just an environmental concern – it carries serious consequences for people, climate stability and global biodiversity. According to a new World Resources Institute (WRI) report, the world lost more primary rainforest in 2024 than in any other year in at least the last two decades. The WRI defines primary forest as “old-growth forests that are typically high in carbon stock and rich in biodiversity”. …Human activity has dramatically reduced ancient forests worldwide. Take the UK, for example, which was at one time thought to be 75% covered by wildwood. Today, that figure is just 10%, with only a quarter of that being ancient woodland. …How can we break this cycle? It starts with tackling the problem at both ends: preventing deforestation and reducing greenhouse gas emissions.
