TAILIEUCHUNG - Perlman - Practical Ecology for Planners, Developers and Citizens - Chapter 1

Part One HUMANS, NATURE, AND INTERACTIONS All organisms live in ecological communities just as all people live in human communities. Often, however, we tend to forget that human communities also exist within an ecological context—that we cannot survive without the natural world around us. | Part One HUMANS NATURE AND INTERACTIONS All organisms live in ecological communities just as all people live in human communities. Often however we tend to forget that human communities also exist within an ecological context that we cannot survive without the natural world around us. In this first part of the book we consider some of the ties between humans and the ecological settings in which they live. We also begin to explore how humans can manipulate these ties for better and for worse. Chapter 1 discusses what nature can do for us if we carefully plan interactions between human and ecological communities as well as what nature can do to us if we are not careful. We also emphasize the importance of context and the need to think beyond the boundaries of official planning domains to create ecologically based plans and designs. In Chapter 2 we introduce the Earth s living components collectively known as biodiversity. Biodiversity is the focus of ecologists who try to understand how organisms interact with one another and their physical environment and of conservationists as they determine how best to protect biodiversity. We explore different reasons why planners designers developers and citizens may want to protect biodiversity as well as the reasons that the native biodiversity of a region is especially valuable. Humans have significant impacts on the environments in which they live impacts that over time can lead to the rise and fall of entire civilizations. Chapter 3 discusses different types of human impacts and lays the groundwork for thinking about how we can lessen these impacts which is the focus of Part 3 of this book. 1 Humans Plan A man a plan a canal Panama.
