ABSTRACT
Our environment has been changing dramatically in recent decades. Important factors contributing to the changes include a growing world population, global warming, expanding industrialization, and advancing technology and economics. Some other changes are worsening air and water pollution, mounting solid waste, acid rain, depletion of the ozone layer, and increasing endocrine disrupters in the environment. These changes have profound impacts on the health and well-being of living organisms. Some of the major issues are discussed here.
