Global climate change can alter environmental conditions. Species and populations may be lost if they are unable to adapt to new conditions or relocate. The diversity of life enriches the quality of our lives in ways that are not easy to quantify. Biodiversity is intrinsically valuable and is important for our emotional, psychological, and spiritual well-being. Some consider that it is an important human responsibility to be stewards for the rest of the world's living organisms.
Diversity breeds diversity.
Having a diverse array of living organisms allows other organisms to take advantage of the resources provided. For example, trees provide habitat and nutrients for birds, insects, other plants and animals, fungi, and microbes. Humans have always depended on the Earth's biodiversity for food, shelter, and health. Biodiversity also supplies indirect services to humans which are often taken for granted. These include drinkable water, clean air, and fertile soils.
