From providing shade, raw materials and food to functioning as large carbon storage reservoirs and a green lung, the world’s forests play a crucial role. They are one of the planet’s most versatile habitats, home to a huge diversity of plants, animals and insects. But the green cover is increasingly under threat from climate change and growing populations. At the same time, increasing numbers of people are campaigning against deforestation, mining, monocultures and urbanization that are destroying forests. It’s reason enough for Global Ideas to take a closer look at the complex ecosystems of forests. We bring you a selection of our best reports, articles and photos on various aspects of the topic. It marks the beginning of our special summer program. Over the next weeks, we’ll be taking another close peek at two other ecosystems - oceans and deserts.
