According in Buddhist philosophy, the name for the physical world, loka, also refers to the physical and mental nature of human beings. The Buddha's teachings consider human beings to be inseparable from the physical world. Therefore, the environment can be three-fold: Physical, mental, and social. Examples of the physical environment are well known –the flora and fauna, the surrounding terrain, climate, and other natural elements of the physical world. Our mental environment includes the conditions that either help, or hinder, intellectual, spiritual, religious, and ethical development. Finally, our social environment is defined by our relationship with other humans, as well as the larger community around us. According to ancient Buddhist commentaries, there are groups of natural laws or cosmic order that interact with the environment such as: Physical, or inorganic laws, organic laws, moral laws, psychological laws, and causal laws.
