CO2 has a large impact on us - human activities, plants, animals, basically everything on this planet. In agriculture, CO2 is vital for photosynthesis, and increases in CO2 concentration could be beneficial to crops such as wheat, rice, soya beans, etc. [Source: Climate Change and World Agriculture] Whereas, a high CO2 level may lead to asphyxiation in humans and animals. The CO2 emissions trapped inside the atmosphere are the major factor of global warming. CO2 also results in ocean acidification, which creates tremendous harm to marine life.

The CO2 level is also an important indicator of whether the air quality in the room is sub-par,  which will suggest when we should turn on the HVAC (heating, ventilation, air conditioning) system in indoor environments no matter for offices, homes, or gyms to increase air circulation. Thus, accessing data on the CO2 level is important for humans to detect potential problems. When sufficient scientific data are available, we will know what actions to take under different circumstances more effectively.
