Ecology, Environment and Pollution 

Ecology is the scientific study of the distributions, abundance and relations of organisms and their interactions with the environment. Ecology includes the study of plant and animal populations, plant and animal communities and ecosystems. Ecosystems describe the web or network of relations among organisms at different scales of organization. An ecosystem is a self-contained, dynamic system made of a population of species in its physical environment. This concept is used to study the complex interactions between the organisms-plants, animals, bacteria, and fungi-that make up the community. There are many different ways in which the community of organisms interacts. Environment means everything around to a living being. Especially the circumstances of life of people or society in their life conditions. It comprises the set of natural, social and cultural values existing in a place and at a particular time, that influence in the life of the human being and in the generations to come. Pollution is anything that makes the earth dirty and unhealthy. Land, air, and water are all affected by pollution. Pollution takes up space on our land. Many of the things people use every day come in packages, like food, games, school supplies, and electronics. Environmental science is the systematic study of our environment and our proper place in it. A relatively new field, environmental science is highly interdisciplinary, integrating natural sciences, social sciences, and humanities in a broad, holistic study of the world around us. The aim of the present book is to provide its readers an acquaintance with the recent research trends in the area of ecology, environmental science and pollution.
