Biodiversity elements with actual or potential use should not be lost simply because we presently do not know their value. Which of the following statements best reflects/reflect the reason/reasons for the above statement?

I. They may have values unused at present but once discovered could enhance the well-being of mankind.

II. They may become useful in future due to changing circumstances.

Select the correct answer using the code given below.

The statement highlights the option value of biodiversity, which refers to the potential future benefits humans might derive from species that are currently not utilized. Statement I is correct because many biological elements contain genetic information or chemical properties that, once discovered through bio-prospecting, could provide new medicines, food sources, or industrial materials, significantly enhancing human well-being. Statement II is correct because environmental and social conditions are dynamic. Species that appear redundant today may become vital in the future due to changing circumstances, such as climate change, the emergence of new pathogens, or the depletion of other resources. For instance, wild relatives of crops may carry genes essential for developing climate-resilient varieties. Therefore, preserving biodiversity acts as an insurance policy for future generations.
