Carbon is a culprit behind many health problems in today's world. Carbon emits from a popular way of how we get energy; burning fossil fuels. We emit carbon when we drive our car, heat/cool our homes, burn wood, and even cut down trees. Humans have emitted mass amount of carbon into the atmosphere already, and now we have a reaction of global warming. Just like Newton said "every action has a reaction".
I think that carbon is important to know because you cant fix what you don't know. Global warming is a popular topic between many environmentalists, and becoming popular with today's society. Carbon is a major part of greenhouse gasses and just as big of a reason for global warming. Learning is the first step to knowing, which is the first step to fixing!
