John Vidal shines a light on communities across Africa, Latin America and Asia fighting to protect their land, water and livelihoods (Land defenders call on UN to act against violence by state-funded and corporate groups, theguardian.com, 21 September). The efforts of these land rights defenders benefit us all. The forests and land they fight to protect provide globally important carbon stores, havens for wildlife, life-saving medicines and clean water for millions. But these lands are often sacrificed to grow crops or mine metals that end up in our everyday lives. As consumers, we should use our collective purchasing power to send a clear message to businesses that these lands – and their people – matter, and they should be protected.
