In BIBLICAL times, TRUMPETS were used to announce the arrival of the king. They sounded to let people to know to prepare for his appearance. Someone of great importance was coming.  Preparation needed to be made.

The TRUMPETS spoken of here in the BOOK OF REVELATION, Chapter 8, are TRUMPETS that herald the coming of JESUS CHRIST - the KING OF KINGS and LORD OF LORDS.  No longer does he come to us as the suffering servant and Lamb of God.  Now He comes as MIGHTY WARRIOR, EVERLASTING CONQUEROR, MIGHTY GOD, and PRINCE OF PEACE.

Now the world will see of Him a side they have not yet seen - the LION OF THE TRIBE OF JUDAH.

Rev. 8:6 "And the seven angels which had the seven trumpets prepared themselves to sound.  The first angel sounded, and there followed hail and fire mingles with blood, and they were cast upon the earth, and the third part of the trees was burnt up, and all green grass was burnt up."

So we can see that the TRUMPET heralds ecological disaster for the unbelieving men and women on the earth. There will be NO GRASS for cattle, sheep, or other livestock. HAIL and FIRE will fall upon all the structures of the earth.  WILDFIRES will be everywhere. BURNING TREES will pollute the skies with SMOKE AND ASH.  With 1/3 of the trees gone, earth's OXYGEN WILL BE DELETED globally, both from lack of trees and grass and from the very consumption of oxygen by the fires. BLOOD WILL POISON THE GROUND.  Crops will fail.  GREAT HAILSTONES WILL FALL.

One thing for sure - it won't be a joke.
