i do belive it is all signs of a deteriating earth that is close to wiping out most living organisms on it's surface AGAIN, but do not believe it is "signs from god" it's simple logic really, leave your god to the unexplainable .....in the last 100 years or so not only has assembly lines and chemical plants (which produce in my own estimate 1000's of times the dangerous gasses that the earth use to recieve) but automobiles have doubled over them selves (in quantity owned by family OR miles driven per day) quite a few times and just to give you an idea of how fast that can add up. in example in numbers: (all are doubled to save myself typing) 1=2, 2=4, 4=8, 8=16...and so on (lets say every year it doubles, by what i've given in the last four years it has become 16 times more congested [THESE ARE ESTIMATES AND GIVEN FOR EXAMPLE PURPOSES I HAVE NOT LOOKED UP TO CONFIRM OR DENY THE ABOVE] and assuming the same goes for all other harmful vapors/chemicals, it's bound to do a number on the earth that protects us. lets just look at one thing these things effect, the ozone. as the ozone fades away, the tempature rises, as that happens we start getting a higher sea lvl (and i know this doesn't really seem possible to some people, but unless you've studdied you just really ahve no idea how much water is packed, frozen solid in the poles) thus throwing off the weight and causing a slightly new orbit/posssibly a new axis the earth spins on by like 0.0000000000000000000000000000000001 of a milimeter....... (and yes no matter how small it may seem to us it really does effect the earth) eventually plates start moving, that causes volcanic actvity along with earth quakes and many other, an earth quake sets a tsunami...and because everything has shifted it effects the size of the earth quake thus chaning the size/speed of the tsunami and leaving us to see something we hardly or never see. at the same time this disruption causes new weather paterns and eventually creating a record number of hurricanes. now don't let this post fool you, this isn't coincidental, it is merely a fact we must face as a species on this earth (or any planent for that matter) that shit will change, and when it does there could be a catastrophic rebound for such a thing. eventually a meteor/comet around the size of the one that whiped out the dinosaurs will hit again, and earth will be continuly slammed with them until IT is gone, even after there are only animals (we can only assume) are left here that are not capable of expressing sorrows before the lord or prayers or redemption plee's it's the way it's worked so far and it will not change because we are here..... you are onto something when you ask if they are signs, but lose it again when you try to connect it to your god,it is just matters of fact.
