I'd read the section in my guidebook about the trail's history the winter before, but it wasn't until now— a couple of miles out of Burney Falls, as I walked in my flimsy sandals in the early evening heat— that the realization of what that story meant picked up force and hit me squarely in the chest: preposterous as it was, when Catherine Montgomery and Clinton Clarke and Warren Rogers and the hundreds of others who'd created the PCT had imagined the people who would walk that high trail that wound down the heights of our western mountains, they'd been imagining me. It didn't matter that everything from my cheap knockoff sandals to my high-tech-by-1995-standards boots and backpack would have been foreign to them, because what mattered was utterly timeless. It was the thing that compelled them to fight for the trail against all the odds, and it was the thing that drove me and every other long-distance hiker onward on the most miserable days. It had nothing to do with gear or footwear or the backpacking fads or philosophies of any particular era or even with getting from point A to point B.It had only to do with how it felt to be in the wild. With what it was like to walk for miles for no reason other than to witness the accumulation of trees and meadows, mountains and deserts, streams and rocks, rivers and grasses, sunrises and sunsets. The experience was powerful and fundamental. It seemed to me that it had always felt like this to be a human in the wild, and as long as the wild existed it would always feel this way. That's what Montgomery knew, I supposed. And what Clarke knew and Rogers and what thousands of people who preceded and followed them knew. It was what I knew before I even really did, before I could have known how truly hard and glorious the PCT would be, how profoundly the trail would both shatter and shelter me.

We shall never fully understand nature (or ourselves), and certainly never respect it, until we dissociate the wild from the notion of usability - however innocent and harmless the use. For it is the general uselessness of so much of nature that lies at the root of our ancient hostility and indifference to it.

Here is your country. Cherish these natural wonders, cherish the natural resources, cherish the history and romance as a sacred heritage, for your children and your children's children. Do not let selfish men or greedy interests skin your country of its beauty, its riches or its romance.

Another glorious feature of many modern science museums is a movie theater showing IMAX or OMNIMAX films. In some cases the screen is ten stories tall and wraps around you. The Smithsonian's National Air & Space Museu, the popular museum on Earth, has premiered in its Langley Theater some of the best of these films. 'To Fly' brings a catch to my throat even after five or six viewings. I've seen religious leaders of many denominations witness 'Blue Planet' and be converted on the spot to the need to protect the Earth's environment

In what terms should we think of these beings, nonhuman yet possessing so very many human-like characteristics? How should we treat them? Surely we should treat them with the same consideration and kindness as we show to other humans; and as we recognize human rights, so too should we recognize the rights of the great apes? Yes.

The question is whether any civilization can wage relentless war on life without destroying itself, and without losing the right to be called civilized.

The Holy Land is everywhere

In every remote corner of the world there are people like Carl Jones and Don Merton who have devoted their lives to saving threatened species. Very often, their determination is all that stands between an endangered species and extinction.But why do they bother? Does it really matter if the Yangtze river dolphin, or the kakapo, or the northern white rhino, or any other species live on only in scientists' notebooks?Well, yes, it does. Every animal and plant is an integral part of its environment: even Komodo dragons have a major role to play in maintaining the ecological stability of their delicate island homes. If they disappear, so could many other species. And conservation is very much in tune with our survival. Animals and plants provide us with life-saving drugs and food, they pollinate crops and provide important ingredients or many industrial processes. Ironically, it is often not the big and beautiful creatures, but the ugly and less dramatic ones, that we need most.Even so, the loss of a few species may seem irrelevant compared to major environmental problems such as global warming or the destruction of the ozone layer. But while nature has considerable resilience, there is a limit to how far that resilience can be stretched. No one knows how close to the limit we are getting. The darker it gets, the faster we're driving.There is one last reason for caring, and I believe that no other is necessary. It is certainly the reason why so many people have devoted their lives to protecting the likes of rhinos, parakeets, kakapos, and dolphins. And it is simply this: the world would be a poorer, darker, lonelier place without them.

So because you are converting it, you are actually conserving it.

The love for God is the love to protect the environment.

The more we get out of the world the less we leave, and in the long run we shall have to pay our debts at a time that may be very inconvenient for our own survival.

Everything is perfect coming from the hands of the Creator; everything degenerates in the hands of man.

The nation that destroys its soil destroys itself.

The earth we abuse and the living things we kill will, in the end, take their revenge; for in exploiting their presence we are diminishing our future.

We lose the forest for the trees, forgetting, even so far as we think at all, that we are trustees for those who come after us, squandering the patrimony which we have received.

It is good to realize that, if love and peace can prevail on earth, and if we can teach our children to honor nature's gifts, the joys and beauties of the outdoors will be here forever.

The world to-day is sick to its thin blood for lack of elemental things, for fire before the hands, for water welling from the earth, for air, for dear earth itself underfoot.

Do no dishonour to the earth lest you dishonour the spirit of man.

The long fight to save wild beauty represents democracy at its best. It requires citizens to practice the hardest of virtues-self-restraint.
