Conservation - a concern far all of usThe laws of thermodynamics tell us that the entropy in a closed system increases, which means that systems go from order to disorder, thus explaining e. g. that a key manufactured from ore will turn into ore again if no energy is invested in maintaining it as a key. Objects can be degraded not only by chemical or physical processes, but also by biodeterioration. The later is processed by infestation from mould or bacteria or by insects, rodents etc.
