Read the passage and answer the question.

The paper industry, often assumed to be in decline amid digital communication, has instead diversified. While demand for newsprint and office paper has fallen sharply, packaging paper consumption has surged, driven largely by the growth of online retail and its reliance on cardboard shipping boxes. Mills that once produced only printing paper have retooled machinery to manufacture corrugated board, a shift requiring substantial capital investment but yielding steadier long-term demand. Specialty papers—used in filters, banknotes, and medical packaging—represent a smaller but highly profitable niche, commanding premium prices due to their technical specifications. Environmental pressure has also reshaped the sector, pushing producers toward recycled fiber and closed-loop water systems, changes that reduce costs over time even though initial conversion is expensive.
