The End of Days

The hard truth is that, no matter how infinite this universe may seem to be, all of its known elements today have finite lives - and everything will eventually end. From galaxies, to stars, to planets...

Our Sun, just like any other star, goes thru a life cycle. It is relatively young, but in 5.4 billion years it will eventually consume its Hydrogen fuel and will begin a drastic transformation affecting the Solar System. Because of its (naturally) increasing luminosity (which can be 'felt' every millions of years), there will be significant global warming and some or most of Earth's eco-system & species will dissappear in 500million yrs time. By 2 bn yrs, max - our oceans will completely evaporate, and with it - all life forms on Earth will also die out.

Scientists predict that after humans (a few thousand yrs from now if we're lucky) - Earth's life will continue to flourish and human existence (in time scale) will just be a mere 'blink of an eye' in geological terms. Human Earth time is short-lived. We just started our history, but sad to say - we're ending it so soon.

But that is NOT THE ISSUE at hand. The issue is we're ending it quite rapidly... as we're currently killing our own livable environment.

The single goal of conservationists (or environmentalists) is really just to slow down the "end process", to buy time and hope for a bit of extended future for humanity... and who knows, maybe an extended time will bring us some miracle that will allow us to outlive our Sun.
