What is CO2?
CO2 is the chemical abbreviation for Carbon Dioxide, which is a natural gas emitted by all living species on the planet. Our air is a combination of different gases such as O2 (Oxygen) and CO2 (Carbon Dioxide) which naturally exist in an equilibrium creating the live friendly sphere that we all live in.
The existence of this gas per se is not a problem, however if there is too much CO2 released into the air, as it is the case these days because of airplanes, cars and other emitting causes in combination with deceasing amounts of plants to filter the air as a result to deforestation, the natural equilibrium of gases and chemicals in the environment gets disrupted, leading to environmental changes and problems, such as global warming and climate change.
