Question

is population advantage or disadvantage​

Answer 1

Answer:

A population decline (or depopulation) in humans is a reduction in a human population caused by events such as long-term demographic trends, as in sub-replacement fertility, urban decay due to violence, disease, or other catastrophes. According to a controversial theory: shrink and prosper, the accompanying benefits of depopulation could be identified after the post-Civil War Gilded Age, post-World War I economic boom, and the post-World War II economic boom.
