Here I will set out common arguments made by those who believe overpopulation does not exist, or is not a problem.

Common arguments (foolproof/general consensus):

• Fertility rates/population growth rates are dropping. Population growth will peak, causing population to decline eventually.
• Population growth has not led to mass starvation, in fact relative poverty has declined in the last decades.
• Food supply has risen to meet demand.

Common arguments (debatable/speculative):

• Fertility rates/population growth rates are dropping, so population growth will peak, causing population to gradually decline eventually. (Proponents may argue that decline will be abrupt due to some crisis)
• Food production is currently sustainable. (Proponents may argue that it is not)
• Overpopulation as an issue has led to human rights violations e.g. forced sterilization (population control programs) in developing countries. (I have found only anecdotal evidence. Most references to forced sterilization is related to eugenics, not population control, and have occurred between 1900s and 50s.)
• Population control programs serve (only) to pre-empt mass-immigration and/or establish a permanent presence in developing countries.
• Overpopulation as an issue serves (only) to legitimize dealing with immigrants/immigration and/or deflect attention from the issue of unequal global distribution of wealth.

Actual problems perceived:

• Decline in fertility rates will cause developed countries to heavily rely on mass immigration from developing countries. This has severe social and economic consequences.
• Decline in fertility rates in combination with population ageing, will lead to various social and economic problems, e.g. ratio labor force/population.

Common fallacies:

• Population densities show by example how overpopulation is not occurring. (Population density ignores use of outside resources and land)
• There is no correlation between population density and wealth/poverty. (Authors are unfamiliar with the concept of import/export, economics, etc.)
• Food production is at x percent of Earth’s capacity. (The question is not a matter of capacity, but of sustainability i.e. can food resources expand, replenish, be substituted, be recycled etc.)
