The earth receives about an astonishing 8.2 million “quads” of Btu energy per year... out of which entire human race uses about 400 quads of energy (in all forms) per year.. One need to give thought on a question “how much energy from earth is dissipating back to solar system..? it can be closely approximated to only 30% of daily gain...thus energy store in the earth is increasing day by day...this energy accumulation can be considered as main cause for all type of catastrophes on earth... same kind of changes are happening on other planets of solar system which are out of human knowledge.
As sun is expanding, the rate of energy infusion will go on increasing... at time span of 5 billion years sun will have radius beyond the earth’s orbit i.e. 250 times the present radius.. sun will swallow the planets one by one... now the term is of Mercury, then Venus and Earth... intrestingly because of electromagnetic and gravitational force of sun, new planets will be formed at outer periphery (100AU) of solar system... tenth planet 2003 UB313(Eris)-baby planet of solar system, is the latest known planet formed by same phenomenon.
Threats like Cyclones, Earthquakes-Tsunamis, Temperature rise, melting of glaciers, Storms-floods all these are preliminary warnings of earth to say now it’s too old to feed living organisms anymore... something more verse than above disasters are yet to happen... a movie-2012 directed by Mr. Ronald Emmerich, is an attempt to visualise the forth coming catastrophes.
In Indian theosophy it is already stated such devastations as a ‘Bhumi Pralaya’... there is mention in “Vishnu Puran” where Lord Vishnu, will lead a ship carrying Bhraman, few seeds and other requisites to start the life once again... this might be a space ship from Venus to Earth came under the governance of Lord Vishnu (might be powerful engineer or shipbuilder).
Our special interest towards Mars and corresponding recent explorations, displays the natural struggle human being for survival... for sure Mars is or will shelter the living organisms... as sun go on expanding, Mars will get closer to sun and conditions on Mars will change naturally, such as to give refuge for living organisms... with extensive discoveries, one day man will make his way to Mars through some powerful space ships... thus once again all in new life will start new civilisation and cycle goes on repeating till the end of Sun as a White Dwarf.
In conclusion 'end of earth' is part of solar system... one can put effort to slow the process but can’t stop...! big and small nations should come together to put combined effort to move to safer planet... very short time is left and some more advancement is required from man and machines for Survival of Life... !
