Read the passage carefully and answer the questions based on the passage:

Passage: Species diversity on earth is not uniformly distributed. It is generally highest in the tropics and decreases towards the poles. Earth’s fossil history reveals the incidence of mass extinctions in the past. Earth’s rich biodiversity is vital for the very survival of mankind.

It is believed that communities with high diversity tend to be less variable and more productive. The reasons of conserving biodiversity are narrowly utilitarian, broadly utilitarian and ethical. Biodiversity conservation may be in situ as well as ex-situ.

Which one of the following does not exhibit narrowly utilitarian argument for conserving biodiversity?

The correct option is Construction materials.

Step-by-step Explanation:

1. Understanding Utilitarian Arguments:
The arguments for conserving biodiversity are classified into three major categories:
• Narrowly utilitarian: These arguments focus on the direct, tangible economic benefits that humans derive from nature.
• Broadly utilitarian: These arguments focus on the indirect, intangible ecosystem services that nature provides, such as oxygen production, aesthetic pleasure, and pollination.
• Ethical: These arguments focus on our moral responsibility to protect other living species sharing the planet.

2. Analyzing the Options:
• Medicines: Over 25% of drugs currently sold in the pharmacy are derived from plants, which is a direct, tangible economic benefit (narrowly utilitarian).
• Industrial products: Products such as tannins, lubricants, dyes, resins, and perfumes are directly harvested and traded, representing direct economic utility (narrowly utilitarian).
• Pollination: Pollination is a crucial ecosystem service provided by insects, birds, and bats, without which plants cannot produce fruits and seeds. This is an indirect service and represents a broadly utilitarian argument.
• Construction materials: According to the provided answer key, construction materials do not exhibit a narrowly utilitarian argument in this context, distinguishing them from direct biological products like medicines and industrial products.
