The wood we use to build our homes, the honey produced by bees, the willow trees that provide us with the source of aspirin -- these are just a few examples of how we rely on our planet's flora and fauna. But we are destroying their habitats. Forests are being decimated to make way for dam projects or farmland, forcing the animals living there to retreat to ever smaller areas.
At the same time, people are only exploiting a fraction of nature's potential. Of the 80,000 species of trees that have been identified, only 800 have been studied for their potential benefits to humans. Many are likely to become extinct before we get the chance to research them thoroughly.
There is, however, some good news. Deforestation around the world is slowing and the international community has set the goal of preserving biodiversity, as detailed in the UN Sustainable Development Goals, which have been explored in-depth in SPIEGEL ONLINE's Expedition BeyondTomorrow special.
