Exponential growth

The exponential growth of human population peaked in 1987. That year 87.01 million more people were added to the Earth. Since 1987, the population has declined on average by 2.1 million less people added per year. In the year of 2000 the population increased by little over 60 million people. If we maintain this 13 year average of 2.1 million less people added per year, we will peak in population reaching zero population growth in 2029 with 6.90 billion people.
