Answer :
According to the ideas of Thomas Malthus, the predicted changes to the human population after 2050 would align with the concept known as Malthusian theory. This theory suggests that population growth will eventually be limited by environmental constraints, particularly the availability of resources like food and living space.
In this context, the correct answer would be:
OC. Eventually the population would stop increasing or would decrease, due to lack of food and living space.
Malthus believed that if population growth continued unchecked, it would outpace the ability of the Earth to provide enough resources to sustain the growing population. This would lead to a point where the population growth would be restricted by factors such as food shortages and insufficient living space, resulting in either a stabilization of the population growth or a decrease in population size.
It's important to note that Malthusian theory has been a subject of debate and criticism over the years, and the actual outcome may vary based on various factors such as technological advancements, changes in resource management, and societal policies.
