Overpopulation is the reason why the Earth is warming. Unless we can drastically reduce the world’s population, we cannot do anything about climate change.
Fact:
Overpopulation is a serious problem and is putting great stress on the planet’s resources. However, it is not the main factor driving climate change. A person’s environmental footprint is calculated by the following formula: Impact = Population x Affluence x Technology (I = PAT). The fact is, while population might be great in many poor countries, affluence and technology are not. Most of our greenhouse gas emissions are a result of these latter two factors, and originate in the wealthy nations, not the developing ones. [China is the main exception to this, although it should be noted that most of its CO2 emissions are generated by its upper and middle classes, not its poor. This will change, of course, as the country continues to develop.] The solution is to be found by changing the technology we use to generate wealth. By using renewable energy, we can go on living comfortable lives without altering the Earth’s climate.
