In fact, the migration of people from rural areas to cities has mostly been good for protecting our forests. There are still indigenous populations that play a vital role in protecting local forests and ecosystems. They live and maintain a balance in these environments. But this only works at a very small scale. For large populations, the migration to cities and intensification of farming has freed up land for forests to return. Billions of us taking up rural living would be a disaster for the world’s forests.
