War: War often leads to lack of resources. This makes it hard for any Lower Developed Country to advance. It also makes it hard for countries to continue producing for trade. Trade: Without trade, MDCs would often exploit LDCs for their natural resources.
Population: Overpopulation, as seen here, happens when population growth outweighs resources. In many places with less resources, birthrates go up. This can happen due to families needing more people in the work field, more crimes going around in the city, lack of education, and lack of resources.
