Respecting environments ensures that communities have adequate resources to meet their needs and many of their wants. Tropical forests provide ingredients for important medicines, for instance, and sustainable use of such resources ensures they’ll continue to exist for future generations. Natural resources provide income for communities as well, both directly and indirectly. Whether communities rely on timber exports, ecotourism or imported raw materials used to produce an end product, natural resources provide livelihoods for communities. Caring for environments around the world by keeping biodiversity high and ecosystems intact ensures that people can continue sharing materials through trade to support their needs.
