Revelation 8

The seventh section of the scroll is opened and the result is a hush throughout heaven (a place normally echoing with praise and joy).  Shortly, seven angels appear each carrying a trumpet.  At the sounding of the first trumpet, 1/3 of earth's vegetation is destroyed.  The second trumpet sounds, resulting in 1/3 of the seas and oceans being destroyed.  The third trumpet brings destruction to 1/3 of the planet's fresh water supply.  The fourth trumpet results in the darkening of the planet's light sources - the sun is decreased by 1/3, 1/3 of the moon and stars are no longer visible.  An angel interrupts this ghastly concert to declare that the remaining trumpets will only bring further turmoil and destruction to the earth.
