Indeed, some analysts claim that overpopulation's most serious impact is its effect on the environment.

A positive check is any event or circumstance that shortens the human life span. The primary examples of this are war, plague and famine. [31] However, poor health and economic conditions are also considered instances of positive checks.

Living costs are a big overpopulation problem.
The positive checks include hunger, disease and war; the preventive checks: birth control, postponement of marriage and celibacy.

Several studies have also found a strong positive correlation between higher military spending and higher carbon emissions where increased military spending has a larger effect on increasing carbon emissions in the Global North than in the Global South. [291] [289] Military activities also affect land use and are extremely resource-intensive. [292]
