1. Discuss the principles and scope of environmental science.

Environmental science came into existence as a substantive and active field of scientific investigation after the 1960s. Rachael Carson’s landmark environmental book Silent Spring played a crucial role in the process by raising concern about environmental issues for the first time. Events such as Santa Barbara oil spill and the Cuyahoga River of Cleveland, Ohio, “catching fire” in 1969 further helped increase the visibility of environmental issues. Since the 1970s, environmental issues have been addressed chiefly in terms of implications of development process on environmental quality. The book Limit to Growth by Club of Rome (1970) and Stockholm Conference (1972) drew the attention of the world community towards environmental imbalance caused by the prevailing patterns of development. In 1987, Brundtland Commission, in its report “Our Common Future”, introduced the word Sustainable Development, which emphasized the need for a development process that takes care of the nature and the welfare of future generations. The Agenda 21 adopted during the Earth Summit at Rio de Janeiro (1992) and the World Summit on Sustainable Development at Johannesburg (2002) also contributed significantly to increase awareness about the need for making the development process eco-friendly.

An increasing level of concern about environment was reflected in the creation of a number of international environmental agencies and non-governmental organizations (NGOs), including United Nations Environmental Programme (UNEP), International Union for Conservation of Nature and Natural Resources (IUCN), World Wide Fund for Nature (WWF), and Global Environmental Facility (GEF). Similarly, numerous scientific and policy-related forums and conventions were held for settling environmental issues, including Ramsar Convention for conservation of wetland fauna and flora, Montreal Protocol for protecting the ozone layer, Intergovernmental Panel on Climate Change (IPCC) for quantifying the extent of global warming, Kyoto Protocol for reducing emission of greenhouse gases, and Convention on Biological Diversity (CBD) for preserving the rich biodiversity of the planet.

Nature of Environmental SCIENCE

Environmental science is the study of all the components or factors that make or influence our life-supporting biophysical environment, including earth processes, ecological systems, biodiversity, natural resource, alternative energy systems, climate change, various types of pollutions, and so on. These entities or processes are guided by complex interaction of physical, chemical, and biological processes, as well as significant human intervention. Therefore, environmental science integrates information from a number of other disciplines and thus is multidisciplinary in nature. Disciplines such as biology, chemistry, physics, geology, geography, sociology, economics, management, and ethics have largely been integrated to develop different subdivisions of environmental science. Its major subdivisions include ecology, geosciences, environmental chemistry, atmospheric science, environmental microbiology, environmental toxicology, environmental impact assessment, and so on.

Besides these, there are certain subdivisions—environmental studies, environmental engineering, environmental economics, environmental ethics, environmental management, environmental sociology, environmental biotechnology, and so on—that are generally treated as independent academic disciplines parallel to environmental science. Environmental conservation is the main emphasis for most of these disciplines, but the approaches vary. For example, environmental studies incorporate more of the social sciences for understanding human relationships, perceptions, and policies towards the environment. Environmental engineering, on the contrary, focuses on design and technology for improving environmental quality.

2. Describe various environmental issues at global, regional and local levels.
