One picture which is self-explanatory.
(from Our World in Data)
the rate of growth peaked in 1962 and has since been on the decline. The following visualization presents this comparison by superimposing the annual population growth rate over the total world population for the period 1750-2010, as well as projections up to 2100. In the projections you can see that by 2100, the growth rate is estimated to fall to 0.1%.
After 2100, population growth will be negative and it will be the population implosion that will be the challenge of those times.
