‘The Earth’, one of our planets in the solar system possesses life of all kinds since millions of years. At present, there is a need for retention of life for the future generations protecting the planet, from the surrounded variations in the atmosphere and environment, namely- green house gases – deeply routed under water and on the surface, as well as on the lower/ upper atmosphere of the Earth. These pollutions or emissions like carbon dioxide (CO2) and methane (CH4) are responsible for the changes in the seasonal climatic variations and earth’s temperatures resulting global warming. Few indications and symptoms for climate change are variable rainfall pattern, melting of glaciers, increased temperatures, excessive flooding and water scarcity. The causes behind this phenomenon are nothing but the generated phenomenal actions by the living beings on Earth, disrupting the existing gifted Nature, drastically into unbearable fearful situations, causing severe losses to the living conditions of human beings and their healthy environments. Control, prevention and elimination of these emissions are possible through the implementation of carbon- free technology systems replacing existing fossil fuel and coal based devices. Full utilization of solar radiations incident on Earth along with the sources of water, for multiple applications like energy, power and fuel (H2) production is inevitable. Major and critical procedures recommended for adoption are highlighted, formulated and analyzed in this paper, indicating the feasibility of methods to save the planet Earth assuring security, safety and protection from global variations.
