Depopulating is a term that refers to the reduction in the number of people or living beings in an area. The opposite of depopulating would be repopulating, which means to increase the number of individuals or living beings in a particular area. Another antonym for depopulating is enhancing, which refers to improving the overall environment of a place, making it a more attractive location for people and living organisms. Alternatively, the antonym of depopulating could also be thriving, which would mean that a place has a high concentration of people or living beings, and they are flourishing, growing, and prospering. Ultimately, it is essential not to depopulate and strive to repopulate and enhance the environment.
