Understanding the Answer

Let's break down why this is correct

Answer

Preserving existing buildings saves the energy that would be used to demolish and rebuild, keeping the embodied carbon in the structure and reducing waste. It keeps the historic streetscape and community identity, which encourages people to live, shop, and work nearby instead of driving long distances. Reusing a building often requires fewer new materials and less construction pollution, so the overall carbon footprint drops. For example, converting an old factory into loft apartments uses the same walls and roof, avoiding the emissions of producing new concrete and steel. This practice keeps resources in use longer, making urban growth greener.

Detailed Explanation

Keeping old buildings means we do not need to make new bricks, wood, or steel. Other options are incorrect because Some people think old buildings always raise prices, but prices depend on many things like location and market trends; Preserving a building does not mean it never needs work.
