The quicker we humans learn that saving open space and wildlife is critical to our welfare and quality of life, maybe we'll start thinking of doing something about it.

The continued existence of wildlife and wilderness is important to the quality of life of humans.

No matter what happens in our life, its our thinking that determines its quality.
