CO2 is a colorless, odorless gas that is essential for life on Earth. In the right concentrations, it is not toxic. However, when concentrations are too high, it can be hazardous to human health.
Effects of High Levels of CO2
At high levels, CO2 can cause dizziness, headaches, nausea, vomiting, and difficulty breathing. In extreme cases, it can lead to death. In addition, high levels of CO2 can also cause an increase in the risk of heart attacks and strokes.
Sources of High Levels of CO2
High levels of CO2 can come from a variety of sources. In enclosed spaces, such as a car or a house, CO2 can build up from lack of ventilation. In addition, burning fuels such as coal, oil, and natural gas can also contribute to higher levels of CO2.
Preventing High Levels of CO2
To prevent high levels of CO2, it is important to ensure that enclosed spaces are properly ventilated. This can be done by opening windows and doors or using fans and air conditioning. It is also important to reduce the burning of fuels as much as possible. This can be done by using renewable energy sources, such as solar and wind power.
