Atheists. Why would anyone nearly 2000 years ago even think that man would be capable of destroying the earth?

when the means of doing so didn't occur for mankind until just the past 100 years or so since entering the "Industrial Age" so that he would write those words down at Revelation 11:18? Man did not have the means to pollute the earth, cause oil spills, cause Global Warming, climate change, did not have the means to deplete the Ozone, make toxic land fills(Love C), make toxic by products, or pollute our oceans, he did not cause nuclear wastes, or nuclear disasters(Chernobyl). There are huge Texas size garbage floats in both the Pacific and Atlantic Oceans. We have cars,trucks,planes,trains,lawnmowers,rot… blowers, and so on, all contributing to air pollution. None of these things existed nearly 2000 years ago so that man would be capable of destroying the earth, so why would anyone even think it possible? Why would they write it down? Add that to the end of days prophesies of Matthew 24:4-14 of which we have unceasing wars now, earthquakes of significance are on the rise, people are starving and malnourished even in wealthy nations as the U.S.A., diseases are on the rise and ones once thought eradicated are making a comeback, and then the prevailing attitudes of men in the last days found at 2 Timothy 3:1-5 and I have to ask, How can you deny God's existence. No one would have even thought such things nearly 2000 years ago because they did not exist at the time. But God knew and had his prophets write them down as a warning for us. Are you ready? The time left is short.
