Changes that are irreversible typically involve permanent alterations to the fundamental structure or composition of a substance or system. Examples include chemical reactions, such as combustion or rusting, where the original materials cannot be recovered. Additionally, certain physical changes, like the destruction of a habitat or the extinction of a species, also represent irreversible changes. Once these transformations occur, restoring the original state is either impossible or highly impractical.
