Question
In the paragraph below, it talks about "This acceleration in growth rate will likely begin to decrease in the coming decades" , which is demonstrated in the figure, as starting from 2012, it takes longer time for the addition of each billion human beings compared to the past. Provide explanation(s) why the human population growth is going to slow down? (Note: slowing-down of growth population decrease)
A consequence of exponential growth rate is that the time that it takes to add a particular number of humans to the population is becoming shorter Figure 19.10 shows that 123 years were necessary to add 1 billion humans between 1804 and 1930, but it only took 24 years to add the two billion people between 1975 and 1999. This acceleration in growth rate will likely begin to decrease in the coming decades. Despite this, the population will continue to increase and the threat of overpopulation remains, particularly because the damage caused to ecosystems and biodiversity is lowering the human carrying capacity of the planet.

The population will fall downdue to limited supply of food and clean water.Many people will die due to this.The fertility rate is falling in most of the countries which creates a big problem.The number of immigrants birth is also falling significantly.Some parents do not want to have a child and just want to live together.The number of infant deaths are on the rise due to lackof good medical aids.
