In this project, we have discussed many times the raw facts of carrying capacity and population growth in relation to math and specific countries. However, there are grave problems created by overpopulation that will only continue to get worse as human population approached carrying capacity. One of these effects is the worsening of climate change. Recently, much has been rightfully made of the issue of climate change, as Earth’s atmosphere continues to warm, endangering all of us. Everyone contributes to this problem by simply existing: using electricity, goods, or any manufactured product contributes to the growing problem. Simple logic will then tell us that more humans means more severe climate change and more severe consequences. One specific result of climate change is desertification, the creation and worsening of deserts, making already dry areas practically unlivable. This process has a devastating effect on humans, forcing them to uproot and move their entire lives elsewhere. This, in fact, was a small part of a film on refugees and migration I watched recently, Human Flow. In this film, there was a feature on sub-Saharan Africans who were forced to migrate from their homes due to desertification. Unfortunately, as with other refugees, they had a hard time getting into Europe and other seemingly welcoming places, not to mention the struggles they faced traveling to new lands. This is just one example of the very real effects of climate change, and by proxy overpopulation and population growth, on humans everywhere.
