Traditional Poetry: The Ballads
The set of anonymous and traditional ballads, called “old ballads” to differentiate them from those written by known poets in later centuries (referred to as “new ballads”), seems to have originated from the fragmentation of medieval epic poems. In this process, each hemistich of the epic poem became a full line with a caesura in the ballad. However, while this theory may apply to epic ballads, others are directly related to traditional lyric poetry. The oldest known

1. Environmental Science and Ecosystems
The natural world is organized into interconnected units called ecosystems. An ecosystem consists of a physical environment characterized by factors like temperature and moisture, the organisms that inhabit it, and the relationships between them.
Since the advent of humankind, human activities have allowed us to obtain food, housing, and transportation. This means we extract resources from ecosystems, impacting the environment. Humans are also subject to natural
