Sore throat is a symptom, not a disease. In each case, there was a different cause that dictated a different treatment. The scratchy throat probably was a mechanical problem caused by dry, heated winter air and aggravated by my friend's tendency to breathe through her mouth when she sleeps.
Definition. Carbon-storing natural feature (such as a forest or the land mass) that exchanges carbon with other reservoirs. A reservoir from which no outflow of carbon compounds takes place is called carbon sink.
Thus, reducing carbon dioxide emissions in order to stabilize atmospheric CO 2 levels is crucial. The carbon capture and storage (CCS) schemes generally consist of three major steps: CO 2 capture, transportation, and sequestration.
