I do not identify as Christian, but I did at one time as I grew up in a Christian household and I have read the Bible.
One thing that I know for sure is that the Bible says there will be tribulations and signs, but that NO ONE will know when the end of the world is really here.
So you'll pardon me if I utterly disregard the beliefs of people who run around shrieking that we're living "in end times."
That is a cult belief. It is neither Biblical nor scientific.
If you want to say, "the world is in chaos because people are harming their environment." Then fine, very well, people very well could destroy themselves (though the earth will surely still be here without us) by wrecking the environment at the pace that they are.
But that belief has everything to do with science and nothing to do with religion.
