The world around us changes all the time; the only thing that is constant is change. Old things and old ways die out from disuse or undergo major changes, while new, previously unknown or little-known sciences and occupations emerge as a corollary of technical progress.

Human impact on the environment has never been greater than in the last hundred years.
