Revelation 9:20 attributes the calamities in Revelation chapters 8 & 9 to the love mankind has for the things his hands produce. Today, the things mans hands produce are primarily produced through industry burning fossil fuels. When Revelation 8 then describes 1/3 of earth's resources being destroyed, we can then recognize these by what we see occurring today by climate change caused through the use of fossil fuels and affiliated means.
As the Lord's angels provide mankind with true illumination as to what will result in the endeavors mankind contemplates to undertake; when the first angel sounds providing mankind with illumination that his undertakings will result in dire environmental consequences, the world’s ruling parties will nevertheless choose to disregard the angels warning, resulting in 1/3 of earth’s trees and all green grass being burned (Revelation 8:7).
Today due to the world’s leaders and titans of industry disregard of global heating caused by increased burning of fossil fuels, the earth as a result is experiencing increasing forest fires throughout many regions.
As the second angel’s sounding warning is also disregarded by the powers that be; a great mountain burning as with fire is then cast into the sea causing 1/3 of earth’s seas to become blood (Revelation 8:8-9).
Today due to agricultural runoff in conjunction with global heating, algae blooms, often referred to as red tides, are becoming more frequent occurrences throughout the worlds oceans, and are causing the death of increasing levels of marine life.
When the third angels sounding illumination of truth is disregarded, a great star burning as a lamp falls upon 1/3 of earth’s rivers and underground aquifers causing them to become bitter and poisonous (Revelation 8:10-11).
Today due to hydraulic fracturing (often referred to as fracking), ever increasing freshwater resources are being made bitter and poisonous.
The star, called wormwood who falls from heaven burning as a lamp is then realized as one of Satan’s angels who provides mankind the illumination for the chemical cocktail to access natural gas from shale deep beneath earth’s surface.
At the fourth angels disregarded sounding warning, 1/3 of the light from the sun, moon, and stars is darkened, and do not shine for 1/3 of the day and night (Revelation 8:12).
Today due to industrial pollution, along with automobile and other atmospheric pollutants, the light from our sun, moon, and stars are considerably less visible than prior to when the industrial revolution began.
