The Effect of CO2 on Humans: A Deep Dive into Carbon Dioxide's Impact on Health Introduction Carbon dioxide (CO2) is a naturally occurring gas essential for life on Earth. It plays a critical role in the process of photosynthesis, which sustains plant life, and in turn, the animals and humans that rely on plants for food. However, rising CO2 levels, primarily due to human activities such as burning fossil fuels and deforestation, have raised significant concerns. While much attention is given to the environmental impacts of increased CO2, it's crucial to understand its direct and indirect effects on human health. Understanding CO2 and Its Role CO2 is a colorless, odorless gas found in Earth's atmosphere. At normal atmospheric levels (around 400 ppm or parts per million), CO2 is harmless and a vital part of the natural carbon cycle. However, when CO2 levels rise significantly, they can have adverse effects on human health and well-being. Direct Health Effects of Elevated CO2...
