The University of Copenhagen, in a publication for ScienceDaily, made the point that a biodiversity crisis exists, implying that the loss of species leads to destruction of essential habitats. This habitat loss alters the course of ecological interactions significantly by removing essential living organisms from the systems. Humans rely on other living organisms for their own health through breathing oxygen produced by plants or consuming exogenous products made by other animals. Destruction of the habitats that sustain valuable human resources is seen as a threat by people who cherish biodiversity.

Sometimes, too much biodiversity is a bad thing according to Native Plants and Wildlife Gardens. Many different native species of plants inhabiting a garden require a lot of maintenance that the natural environment fails to provide. Also, over-diversification of plants causes too much species dilution, which doesn't work well to attract insects that serve as pollinators. Too many plants causes high competition, and as a result, some native species of plants are wiped out completely.
