Physical surroundings, including those in which a person lives and relies for daily activities such as respiration, production, and consumption, can be considered part of the definition of the environment. Everything in his physical environment is a part of his ecosystem, including the air, water, and land, as well as the many fossil fuels, earth, and plants and animals that make up his ecosystem. Physical environment and human well-being are intertwined in a variety of ways, including both qualitative and quantitative aspects. With regard to development and its speed, natural resources have a significant role. A considerable portion of the environment in an urbanised civilization is man-made. The creation of artificial settings (like buildings and roads) as well as the means of transportation (like clothing and cars) is dependent on human labour as well as the use of natural resources.
