Explanation

The environment performs several critical functions essential for human survival and economic activity. First, it supplies resources (provisioning services) such as food, timber, fibers, and medicinal plants [4]. Second, it sustains life through fundamental life-support services, including the purification of air and water, nutrient cycling, and the provision of essential gases like oxygen [4]. Third, the environment provides aesthetic and cultural services, which include non-material benefits like spiritual enrichment, recreation, and the appreciation of natural beauty [2]. These functions are often categorized into provisioning, regulating, supporting, and cultural services [4]. Together, these processes maintain biodiversity and support human well-being by providing both tangible goods and intangible psychological or aesthetic value [5]. Therefore, all three listed functions—supplying resources, sustaining life, and providing aesthetic services—are core functions of the environment.
