This book examines the multidisciplinary aspects of the impacts that humans have on the physical environment, the biota, and human health. Focusing on developing and under developing countries, it covers environmental degradation, pollution, occupational health, risk management, epidemiology and toxicology. It will help scientists, resource managers, administrators, educators, policy makers and college students to interpret that risk management and the advancement of research in sustainable development is of utmost importance in seeking solutions for the protection of natural and anthropogenic systems, and human health.
