What does it mean to be carbon neutral?
Carbon neutrality exists when the amount of carbon emmitted into the atmosphere equals the amount of carbon taken out of the atmosphere. For example, if a car emitts 100 pounds of CO2, then the amosphere has gained that much carbon dioxide; however, should a tree absorb said CO2, then net zero carbon will be achieved. Thus it is carbon neutral.
What are the benefits of being carbon neutral?
Climate change
Being carbon neutral means that the carbon blanket surrounding the earth can maintain a habitable earth. This deters global warming because carbon traps heat from the sun; therefore if the amount of CO2 in the atmosphere does not increase then the earth will remain habitable.
Pollution
An exessive amount of carbon dioxide in the atmosphere can hinder life on Earth. With enough carbon, the air will become impure, thus making it difficult to breath and potentially causing health conditions.
