What would happen if the population growth rate reached zero?
Zero population growth refers to a population that is unchanging – it is neither growing, nor declining; the growth rate is zero. Therefore, a country that has reached zero population growth has a population where births plus immigration is equal to deaths plus emigration over the course of a year.
What are the predictions of the population bomb?
It predicted worldwide famine in the 1970s and 1980s due to overpopulation, as well as other major societal upheavals, and advocated immediate action to limit population growth. Fears of a “population explosion” existed in the 1950s and 1960s, but the book and its author brought the idea to an even wider audience.

Earth could continue to host life for at least another 1.75 billion years,
How long can we sustain life on Earth?
Global population is expected to peak around 10 or 11 billion and with care, it’s possible that we may be able to sustain a habitable planet for that many humans more or less indefinitely.
What is the effect of growing population on Earth?
The effect of growing population will be an increased demand for resources and space. Both of which we are running out of. The Earth just can’t keep up with us and our habit of wastage is not helping.
How many Earths will we need in the future?
