The concept of “religion” was formed in the 16th and 17th centuries, despite the fact that ancient sacred texts like the Bible, the Quran, and others did not have a word or even a concept of religion in the original languages and neither did the people or the cultures in which these sacred texts were written.
The history of religion refers to the written record of human religious feelings, thoughts, and ideas. This period of religious history begins with the invention of writing about 5,220 years ago. The prehistory of religion involves the study of religious beliefs that existed prior to the advent of written records.

The main mechanisms by which forests modify weather have been identified. They are the surface albedo, transpiration and evaporation of water vapour, aerodynamic effects, and emission of hydrocarbons whose oxidation can form aerosol particles.
Forests have also sanitary influences upon environment due to the production of oxygen through photosynthesis. Forest plays a major role in reducing various types of pollution such as water, air and noise pollution. Influences of forest upon biotic conditions include its effect on animal life and mankind.
