CO2 Levels in the Atmosphere
The concentration of carbon dioxide (CO2) in the atmosphere has increased significantly since the start of the industrial revolution. According to the World Meteorological Organization, CO2 levels have increased by more than 50 percent since the pre-industrial era and are now at their highest point in over 800,000 years.
CO2 is a naturally occurring gas that is essential for life on Earth. It is produced by all living things as a by-product of respiration and is also released through the burning of fossil fuels.
Health Effects of High CO2 Levels
High levels of CO2 can have serious health effects. Exposure to high concentrations of CO2 can lead to dizziness, headaches, nausea, and increased heart rate. Long-term exposure to high CO2 levels can lead to more serious health problems such as respiratory and cardiovascular diseases.
When is CO2 Harmful?
The World Health Organization (WHO) recommends that indoor air quality should not exceed 1000 ppm of CO2. However, the safety limit of CO2 in outdoor air is much higher, as it can be diluted by the air. The WHO suggests that outdoor air quality should not exceed 5000 ppm of CO2.
High levels of CO2 can also be dangerous in enclosed spaces. For example, concentrations of CO2 in a poorly ventilated room can reach up to 10,000 ppm, which can cause suffocation.
Conclusion
CO2 is a naturally occurring gas that is essential for life on Earth. However, high levels of CO2 can be dangerous and can lead to serious health problems. The World Health Organization recommends that indoor air quality should not exceed 1000 ppm of CO2 and outdoor air quality should not exceed 5000 ppm of CO2. High levels of CO2 in enclosed spaces can also be dangerous, and can lead to suffocation.
