12. DOUBLING TIME THE TIME TAKEN TO DOUBLE THE CONSUMPTION OF ANYTHING IS GIVEN BY DIVIDING 70 BY THE % ANNUAL INCREASE THE ANNUAL INCREASE IN THE POPULATION OF THE WORLD IS 2%, SO THE DOUBLING TIME IS 35 YEARS THE ANNUAL INCREASE IN ENERGY CONSUMPTION IN THE USA IS 7% SO THE DOUBLING TIME IS 10 YEARS

13. WORLD POPULATION DATEPOP xDT (YEARS) 8000 BC51500 1650 AD500200 1850 AD100080 1930 AD200045 1975 AD400040 2015 AD8000??

15. EXPONENTIAL GROWTH A SIMPLE EXPONENTIAL SERIES IS ONE IN WHICH THE LAST TERM IS DOUBLE THE PREVIOUS TERM EG 1,2,4,8,16,ETC A PROPERTY OF SUCH A SERIES IS THAT THE LAST TERM IS BIGGER THAN THE SUM OF ALL THE PREVIOUS TERMS IN THE NEXT 35 YEARS THERE WILL BE MORE PEOPLE BORN THAN IN THE WHOLE OF HISTORY IN THE NEXT 10 YEARS THE USA WILL USE MORE FUEL THAN IN THE WHOLE OF HISTORY

16. CONSUMPTION OF A FINITE RESOURCE 5 TIMES MORE FOR DOUBLE LIFE SUPPOSE THAT 0.01% USED 1/10,000 OF KNOWN RESERVE EXHAUSTION IN 13.3 DOUBLING TIMES FOR DT = 10 YRS, ALL GONE IN 135 YRS

17. ELECTRIFICATION ALL DEVELOPED SOCIETIES SHOW A TREND TOWARDS GREATER USE OF ELECTRICITY THIS MEANS HIGHER CONSUMPTION OF PRIMARY FUELS THIS MEANS MORE ATMOSPHERIC POLLUTION

18. THE INFLUENCE OF THE USA 5% 0F THE WORLD’S POPULATION USING 60% OF THE WORLD’S ENERGY AND PRODUCING MOST OF THE WORLD’S POLLUTION WILL NOT RATIFY THE KYOTO PROTOCOL
