I agree the church needs a new morality which needs to be based on solid foundations.  To give an example.  Two hundred years ago the world population was approximately 1 Billion.  At that time Malthus warned us prophetically and provided us with an explanation of exponential population growth (2 x 2= 4, 4 x4 = 16; 16 x 16 = 256; 256 x 256 =   etc. ) and warned us of the prophecy in Rev. of the 4 horses of the Apocalypse.  In 1930 the world population had doubled.  In the 1970s the world population had tripled.   At that time an ecologist--Garrett Hardin again warned us of the CARRYING CAPACITY OF THE EARTH and that we were nearing the tipping point at which the population growth would no longer be sustainable.  The world population is now over 7 Billion--and increase of over 5 Billion in 80 years.  He provided us with a PARABLE FROM NATURE--the Parable of St. Matthew Island.  One symptom of overpopulation is environmental degradation...no more words left here except..birth control.
