The hazard of O2 deficiency: An increase in CO2 density can lead to O2 deficiency. Living with insufficient O2 increases heart load, lowers blood circulation and harms our organs, especially for children and elders.
Prevent car accidents by monitoring CO2: CO2 density could increase quickly in the limited space because of human breath. Hypoxia makes people sleepy and may cause accidents
