Population growth can be positive for the world, both in terms of the economy and the environment. As a country's population increases, this can have significant positive implications on its economy, as more people are able to purchase goods and services, allowing the economy to experience substantial growth. Following this idea “the more people there are on Earth, the bigger the markets for new innovations” (Mulligan, 2009). So, as a population grows, there is a greater chance that there will be more people with the potential to be innovators who can scale up. technological solutions such as alternative energies or efficient means of food production. Population growth can also contribute to the environment, because if "larger populations consume fossil fuels, they also stimulate the efficient supply of fuels and substitutes" (Kahn, 2005), so that even if larger populations consume more energy, they can also grow in safer, renewable forms of energy that can help protect the environment. This can happen because as technology advances, resources such as oil and coal, which can have significant negative environmental impacts, are pushed aside by innovators who want to develop new technologies. new efficient ways to produce energy without having a lasting impact on the environment.
