• As dissolved carbon dioxide increases, pH becomes more basic

• As pH becomes more acidic, dissolved carbon dioxide increases

The graph shows projections for world population growth. Why do some demographers predict the HIGH world population growth rate on the graph? 

• The effect of lower fertility rates will result in a replacement level for the world population by 2050

• Although the fertility rate in developing countries is decreasing, it is still at a level that will result in a global high rate of growth

• The growth rate will balance the different fertility rates between developed and less developed nations

• The fertility rate of developing countries and less developed countries will become the same
