We all benefit from a rich mix of natural life around us. We call this natural variety “biodiversity”. Without a healthy diversity of plants, animals and other life forms, we wouldn't survive. The connections among these living things keep our environment working. A healthy environment helps to:

● clean the air we breathe
● recycle, purify and store the water we drink
● transform our wastes into resources
● provide us with food, fuel and shelter
● stabilize and moderate our climate
● provide the resources we use for industry and recreation
● nurture and feed our spirits.
The environment does these things for all of us. It will continue to do so if we just protect it and let it function naturally.

The Economics of Ecosystem Services and Biodiversity in Ontario
There are many links between nature and economy. In addition to its inherent value, Ontario’s biodiversity has economic value associated with the goods and services it provides. Ecosystem services include nature’s benefits to us, such as providing us with food, regulating our air and water quality, and moderating the effects of extreme weather we experience, as well as the recreational and spiritual opportunities we enjoy.
