Introduction Impressions of nature spring to mind as we take a quiet morning walk during the early days of March. Here in the Northeast, there is still plenty of snow amid the maple, beech, and cedar trees. The spring thaw has just begun, the air is heavy with fog, and while the winter has been easy, there is enough snow left in the woods to challenge a tall pair of boots. It is a magical time of year. In this wintry region, warm spring days appear hopelessly distant and elusive. But beneath the snow and in the rising sap of trees, the signs of reawakening and rebirth are singing loud and clear. Everywhere we look, water is flowing again! The forest is still carpeted in deep snow, but here and there, streams are playing hide and seek. Irresistibly, we are drawn to these places where short-lived creeks appear and disappear beneath the snow. Within a month, though, these surface waterways will be gone. Without a conscious thought, and with childlike fascination, we follow the course downstream. The first hint is a gentle depression in the snow, then a broad sheet of ice, and finally, much farther along, the first bit of open water. It's just a trickling flow - certainly no Mississippi or Fraser River here, but even those mighty rivers have modest origins. In places, the water meanders unhurried through the thawing earth. Elsewhere, there are narrow and clearly formed rivulets - perfect little streams, flowing fast and wild over gravel and sand. We follow this elusive stream as best we can, but ultimately it seems to disappear without a trace under the snow. Perhaps it continues to flow unseen, carving out a little gorge between the snow and frozen soil. Or perhaps its course takes it on a secret underground route toward a frozen lake. Whatever its actual path might be, we know that these particular waters, and the various pollutants and nutrients that tag along, will eventually enter rivers and lakes downstream, and finally make their way to the sea, No matter where we live, we are all part of an incredible watershed story, and we are all part of nature. Water is essential to life on Earth, and it is constantly on the move. Maybe this is part of our fascination with that meltwater stream, and part of our fascination with every other stream and lake and ocean. Sooner or later, we all stare into a river and wonder where it has been, and where it is heading. When probing the mysteries of a watershed, one can detect many things, both wondrous and worrisome. It is through such observation that we embark on a voyage of discovery and, at the same time, gain understanding and compassion. And because water is a lifeline for us all, it is the natural focus for a book like this one, which serves as an introduction to ecology and environmental issues. In this book, we are addressing three main goals. First, we hope to promote a better understanding of the fundamentals of ecology. Because water is vital to life, we pay particular attention to water-related issues, from the simple concept of a watershed to the biological intricacies of a wetland ecosystem. (A glossary of technical terms used in the text appears on page I46.) With this ecological context in place, we aim secondly to examine and explain the numerous environmental issues affecting the health of natural ecosystems in North America. Finally, we hope that readers will become active in furthering the goals of conservation and helping to protect and restore the environment. We have included "How Can I Help?" sections throughout Part it to illustrate simple things that individuals can do to support the environment.
