the Mass bakwaas

Energy can never be created can never be destroyed .. but can be transformed from one form to another

In my recent research on real estate i was faced with a question (a dilemma actually) .. is the mass on earth increasing .. and i let my mind fly where ever it could reach

the only thing that earth receives from universe is energy (apart from few meteoroids/ asteroids - and all the steroids ;)) .. in form of light form sun moon stars planets etc heavenly bodies
the only thing it gives back to the universe is the terrestrial radiation (apart form sporadic satellites).. again in form of light or energy

so the only thing shared is the energy .. if we consider (from my last knowledge) that photons have a mass .. so the net addition from giving and taking is the mass of photons left on the earth that it does not give back -- like the balance/ surplus of payments.

lets come back to the planet earth .... all the living beings reproduce (sexually or asexually) they consume they excrete .. their offspring consume and excrete .. forget consumption, the DNA (which to my knowledge is the most fundamental block of life) it also comes from somethings that exist on earth .... the earth has the same resources it had since its arguable birth
so if some of the living beings proliferate others would be decimated (rather exterminated)

now to the real estate problem (one of the many many human problems) .. we dig we make a mountain .. we break a mountain we make a mountain . .. we dig we make land on water
bottom line ... Adam is the agent of degradation and aggradation .. so if the population grows the way it is .. we end up more with holes than the houses on face of the land (not so beautiful .. han!!!) .... or may be a single multistory building just before the doomsday .. or may be the funny mind is able to find some alternatives
(बेक़रारी ने मुझे अविष्कारी बना दिया ) .. the question still remains... if all the mass in the world is exploited by single specie (sooner or later) ..for its consumption, reproduction (DNA), housing, blah blah blah .. so what do we have at the end .. a giant ant with the earth's mass in its stomach .. replacing the earth in the universe
isn't this scientific
