Progress in Environmental ResearchNova Publishers, 2007 - 309 страници The environment consists of the surroundings in which an organism operates, including air, water, land, natural resources, flora, fauna, humans and their interrelation. It is this environment which is both so valuable, on the one hand, and so endangered on the other. And it is people which are by and large ruining the environment both for themselves and for all other organisms. This book presents important new research on a wide variety of topics in this field. |
