Current projections show a steady decline in the growth rate, and a population of around 9 billion by the year 2050. The scientific consensus is that the current population expansion and accompanying increase in usage of resources is linked to threats to the ecosystem. The InterAcademy Panel Statement on Population Growth, which was ratified by 58 member academies in 1994, called the expansion in human numbers "unprecedented", and stated that many environmental problems were aggravated by the population expansion. At the time, the world population stood at 5.5 billion, and optimistic scenarios predicted a peak of 7.8 billion by 2050, a number that current estimates show will be reached around 2030. HISTORY OF POPULATION OF WORLD If you were to take a standard sheet of writing paper .1mm thick and cut it into two sheets, placing one atop the other, it would then be .2mm thick. Then, cutting the stack of two and making a stack of 4 sheets, it would then be .4mm thick. Believe it or not, if you continued to do this just one hundred times, doubling the size of the stack each time, the thickness of the stack would be 1.334 x 1012 light-years. This is an example of exponential or geometric growth, where the rate of growth is always proportional to it's present size. Exponential growth also applies to the the human population. It begins growing very slowly, but over generations the growth rate increases more and
