Translation is the communication of the meaning of a source-language text by means of an equivalent target-language text. The English language draws a terminological distinction (not all languages do) between translating (a written text) and interpreting (oral or sign-language communication between users of different languages); under this distinction, translation can begin only after the appearance of writing within a language community.
Hence the vanity of translation; it were as wise to cast a violet into a crucible that you might discover the formal principle of its colour and odour, as seek to transfuse from one language into another the creations of a poet. The plant must spring again from its seed, or it will bear no flower—and this is the burthen of the curse of Babel.
Scientists investigating the impacts of climate change need to understand how multiple environmental stressors combine to affect individuals, populations and ecosystems. In marine ecosystems, stressors appear to have a significant effect on the larval stages of organisms.
