I honestly think no matter WHAT you believe in... if you look at the "signs" or what has been happening, and going on around you in recent times... then YES I think this is the "end of times".
If you know GOD, read your bible, know the bible and pay attention... then you should know or realize if this is not the "end of times" then it is not far off...
Even if you don't believe in GOD... still look at everything... look at the state of the world. Look at how close we are, and have been on the verge of a World War 3... and if you know anything about that, then you should know if there ever WAS a WW3 this world would not survive it. Just look at TV alone... and do not start yelling about freedom of speech when I say this... but just LOOK at what is allowed on TV now, versus even 10 years ago... 20, 50 years ago... Look at what this generation is being taught around them. Look at the LACK of values the average family brings their children up with. Look at all the violence, hatred, and intolerance around us. Look at what human beings are doing to each other. What is on the news every single day. Mothers killing their children, a person killing another person because they looked at them funny, shooting spree's almost becoming a monthly thing... People just don't value human life like they used to. So yeah I can see this being the "end of times" just based on this alone... because I can see the human race destroying itself, or most, just from maybe a WAR, or some other means one day soon.
As for nature... well either way you look at it... you might think GOD is behind this, or that mother nature is behind it, or that it is the human races fault... but however you look at it, it all comes down to the same thing... nature is not doing so well, and it is throwing bigger tantrums more and more often. Nature is kicking our asses all over the world, and nature could be the reason we are destroyed in the end, regardless if you believe GOD is behind it, human beings or just mother nature.
I personally believe that we are in the "end of times". I believe this has to do with GOD and the bible, but I also believe we human beings are playing our own part in it too, in a BIG way. From trashing the earth, to lack of values and morals, and etc...
