Answer 1

Hmm, some factors that affect human population size are the environment, religion, poverty, war, etc. Some factors that control human population size today are contraception, abstinence, abortion etc. Abortions weren't common until the 19th century. Abstinence and contraception was around way back. In past, some control factors were infanticide, genocide, etc.
