Overpopulated areas often face social and economic strains, which can contribute to the emergence of conflicts. High population densities exert pressure on infrastructure, housing, and public services, leading to inadequate access to healthcare, education, and employment opportunities.

Can Mars support life?
Mars is believed to have lost its water when it lost its magnetic field around 4 billion years ago. Without an atmosphere, there was nothing to prevent Mars' water from evaporating and then being lost to space. This radiation also made the existence of life at the surface of Mars unfeasible.
