Biodiversity is important because it paves the way for the evolution of traits that allow species to survive harsh conditions, etc. For example, many farmers used and continue to use the 4-crop rotation system, to enrich the soil with nutrients from a variety of crops. Biodiversity is responsible for all the different animal and plant species (not to mention many others) that contribute greatly to the balance of our fragile ecosystem(s). It provides the setting for the dominant traits in species to prevail, because the greater the diversity, the greater the chance that enough members of a greater number of species will develop the physical (internal/external) traits necessary for their survival.
