Passage : Nature is like business. Business sense dictates that we guard our capital and live from the interest. Nature’s capital is the enormous diversity of living things. Without it, we cannot feed ourselves, cure ourselves of illness or provide industry with the raw materials of wealth creation. Professor Edward Wilson, of Harvard University says, “The folly our descendants are least likely to forgive us is the ongoing loss of genetic and species diversity. This will take millions of years to correct.” Question: The writer compares nature to business as: a) capital depletion in nature and business. b) similarity of both in usage. c) some interest level yield. d) diversity of various capital inputs.
