Ageing
Ageing or aging (see spelling differences) is the process of becoming older. The term refers especially to human beings, many animals, and fungi, whereas for example bacteria, perennial plants and some simple animals are potentially immortal. In the broader sense, ageing can refer to single cells within an organism which have ceased dividing (cellular senescence) or to the population of a species (population ageing).
Increasing concerns about rising atmospheric carbon dioxide (CO2) levels prompted scientists to explore ways of converting this greenhouse gas into fuels and organic materials using light.
