The earth is a living planet where many complex systems run perfectly, without stopping at all compared to other planets, it is evident that is all its aspects, earth I’d specially designed for human life built on delicate balance, life permits in every spot of this planet, from the atmosphere to the depths of earth.
One of the most important balance’s in our planet I’d revealed in the atmosphere that surrounds us. The atmosphere of earth holds the most appropriate gases in the most appropriate ratio needed for the survival not only ox human beings, but also for the living beings in earth. The 77% nitrogen, 21% oxygen and 1% carbon dioxide as well as other gases readily available in the atmosphere represents the ideal figures necessary for the survival of living beings, the vegetation covering the earth converts carbon dioxide to oxygen, producing 190 billion ton of oxygen every day.
In addition to the establishment of ideal gas mixture required for life on earth, the mechanism needed to preserve and maintain this order are created alongside with it any break in the balance though instantaneous, our any change in the ratio even for a very short period, would near the total destruction of life. Yet this does not happen at the same time, the earth has the ideal size in terms of magnitude to possess an atmosphere. If the man of the earth were a little Len, then its gravitational force would be insufficient and the atmosphere would be dispersed in space. If its man were a little greater, then the gravitational force would be too much and the earth would absorb all gases in the atmosphere.
The majority of people spend their lives without being aware of the delicate balances and subtle adjustment in the earth. The creation of these delicate proportions and balances in the sky.
