Population and Environment

The environment affects population through biophysical limitations, behavioral controls, and resource availability. Weather and climate affects of human well-being and health. The study of attitudes of human body to changes in the atmospheric environments is known as human bio meteorology, which lays emphasis on to establish how much of the overall biological variability the result of change in weather, climate, and season is. Three levels of climate environment affect human behavior whereas, micro climate, which represents weather conditions surrounding an individual living thing, ecological climate, its represent weather elements of the habitat of living thing, geographical climate, weather situation of larger area unit and longer temporal span.

Human body can function properly only in certain suites of environmental conditions in terms of oxygen, heat, light, humidity and precipitation, wind, atmospheric electricity and space. Even the survival of human body depends on the above factors. Lack of required amount of oxygen at higher altitudes makes human survival impossible. Excessive heat and humidity retard body and mental growth whereas very high or very low temperature on the one hand adversely affects human body and on the other hand makes food a scarce commodity to support human life.

Various combinations of environment factors have not only affected but conditioned racial characteristics in different parts of the earth's surface. Environment also effect conditions thoughts, ideologies, and culture of human being. Other hand social, economic, and political behaviors influenced to certain extent by man's perception of environmental factor and his response to these factors. Frequency and magnitude of extreme natural events and environmental factors like earthquake, floods, droughts, landslides, and atmospheric storms influence man's perception of natural environment and decide his reactions and response to these events.

The most significant aspect of the environment of the environment in influencing human activity is the availability of natural resources. The rich or poor quality and quantity all the availability of renewable and non-renewable resources decide the type of human activities towards economic viability, social organizations, political stability, and international relations. In matter of fact, the level of economic development largely depends on natural resources.
