By this time the burned out grass will be revived - like grass after a drought.  Much will return to near normal, with even the bitterness gone from the rivers.

Then the Fourth Angel will blow the FOURTH TRUMPET.

Rev. 8:12 "And the fourth angel sounded, and a third part of the sun was smitten, and the third part of the moon, and the third part of the stars; so as the third part of them was darkened, and the day shone not for a third part of it, and the night likewise."

Light will be reduced by one third.  Earth will become a place of deeper and darker shadows. Nights will become darker as even moon and stars grow dimmer.  A dim twilight will fall upon the whole earth.  Peoples eyes will strain to see.  And of course, mankind will try to attribute this darkening to something natural - like a volcanic plume of dust in the atmosphere.

No glory or respect will be given unto God.Rather, men will curse Him for allowing these things to happen to the earth.

Then will begin the next TRUMPET blasts, which will signal the beginning of what the Scripture calls 'the three WOES'.  At that time, more glory will be given to a now extinct civilization known as the Mayas than to the Living Creator - GOD THE FATHER.
