As a branch of astronomy, star formation includes the study of the interstellar medium (ISM) and giant molecular clouds (GMC) as precursors to the star formation process, and the study of protostars and young stellar objects as its immediate products.
Carbon capture and storage (CCS) (or carbon capture and sequestration) is the process of capturing waste carbon dioxide (CO2) from large point sources, such as fossil fuel power plants, transporting it to a storage site, and depositing it where it will not enter the atmosphere, normally an underground geological formation.
Plants use carbon dioxide as part of the process of making energy from sunlight. As part of that process, plants produce oxygen as a byproduct. The process of absorbing carbon dioxide and expelling waste oxygen is referred to as plant respiration. However, unlike animals, plants do not have lungs to help with the process of converting atmospheric gasses into energy.
