The Ecosystem 41 reference to some of these spheres that we will further elaborate our study. The Troposphere To define troposphere, the following excerpt by William Van Der Bijl is quoted: 'The first sphere is termed as the 'troposphere'. The troposphere is a layer of atmospheric air extending about seven miles upward from the earth’s surface, in which the temperature falls with height. As it is directly above the earth’s surface, it is of most immediate concern to mankind. This seven mile layer of gases skirts the earth’s surface and is held there by the force of gravity. It has many functions to perform, the entire life system is supported by this part of the nearest heaven. Moreover, this layer works as a protective cushion. Suspended in the gases are a countless number of particles of solid matter, specks of inanimate dust, and tiny living organisms which are swept aloft from the earth’s surface by the incessant movement of the air. It is this cushion which protects the earth and life on earth from the constant bombardment of stray heavenly bodies. Without this cushion, it would have been impossible for life of any sort to be sustained on earth. Another point worthy of note is that the density of this layer is exactly what is needed and that the size of the layer is made to measure. If the balance were somehow disturbed, this layer would be of no benefit to life on earth. It would rather work to the contrary; the light of the sun and other beneficial rays which must reach the earth, would be fogged out. ' 3
