Michigan Compiled Laws, Chapter 324. Natural Resources and Environmental Protection § 324.35502

(a) The earth's biological diversity is an important natural resource. Decreasing biological diversity is a concern.

(b) Most losses of biological diversity are unintended consequences of human activity.

(c) Humans depend on biological resources, including plants, animals, and microorganisms, for food, medicine, shelter, and other important products.

(d) Biological diversity is valuable as a source of intellectual and scientific knowledge, recreation, and aesthetic pleasure.

(e) Conserving biological diversity has economic implications.

(f) Reduced biological diversity may have potentially serious consequences for human welfare as resources for research and agricultural, medicinal, and industrial development are diminished.

(g) Reduced biological diversity may also potentially impact ecosystems and critical ecosystem processes that moderate climate, govern nutrient cycles and soil conservation and production, control pests and diseases, and degrade wastes and pollutants.

(h) Reduced biological diversity may diminish the raw materials available for scientific and technical advancement, including the development of improved varieties of cultivated plants and domesticated animals.

(i) Maintaining biological diversity through habitat protection and management is often less costly and more effective than efforts to save species once they become endangered.

(j) Because biological resources will be most important for future needs, study by the legislature regarding maintaining the diversity of living organisms in their natural habitats and the costs and benefits of doing so is prudent.
