surely our planet needs to replenish itself every now and then....but if these theories came true...well i guess, it's better for us to know something global is happening on 2012 rather than sitting in our a@#es and not knowing!
reseach shows that when it really happens, water rise will be 340 to 360 ft above the present sea level or that's how they computed it to be after polar melting and after the poles have shifted (you can read more of this at howtosurvive2012.com)
a lot of people are really asking government agecies as to where and how are they going to build bunkers if this world wide catastrophe happens....
well, honestly? if you want to build something? you'll need to secure permits!!!! or otherwise, they'll turn you plan down....sheez!
anyways, in situations like these....humankind will thrive and not annihilation!
