The most powerful argument of all for saving open space is economics; in most states, tourism is the number two industry.
The biggest challenge is how to affect public attitudes and make people care.
I don't think we're going to save anything if we go around talking about saving plants and animals only we've got to translate that into what's in it for us.
Our challenge for the future is that we realize we are very much a part of the earth's ecosystem, and we must learn to respect and live according to the basic biological laws of nature.
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 other thing is quality of life; if you have a place where you can go and have a picnic with your family, it doesn't matter if it's a recession or not, you can include that in your quality of life.
