Environmental science is an interdisciplinary academic field that integrates physical, biological, and geography (including ecology, biology, physics, chemistry, plant science, zoology, mineralogy, oceanography, limnology, soil science, geology and physical geography, and atmospheric science) to the study of the environment, and the solution of environmental problems. Environmental science emerged from the fields of natural history and medicine during the Enlightenment.[1] Today it provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems.[2]

Environmental studies incorporates more of the social sciences for understanding human relationships, perceptions and policies towards the environment. Environmental engineering focuses on design and technology for improving environmental quality in every aspect.

Environmental scientist like the understanding of earth processes, evaluating alternative energy systems, pollution control and mitigation, natural resource management, and the effects of global warming and climate change. Environmental issues almost always include an interaction of physical, chemical, and biological processes. Environmental scientists bring a systems approach to the analysis of environmental problems. Key elements of an effective environmental scientist include the ability to relate space, and time relationships as well as quantitative analysis.

Environmental science came alive as a substantive, active field of scientific investigation in the 1960s and 1970s driven by (a) the need for a multi-disciplinary approach to analyze complex environmental problems, (b) the arrival of substantive environmental laws requiring specific environmental protocols of investigation and (c) the growing public awareness of a need for action in addressing environmental problems. Events that spurred this development included the publication of Rachel Carson’s landmark environmental book Silent Spring[3] along with major environmental issues becoming very public, such as the 1969 Santa Barbara oil spill, and the Cuyahoga River of Cleveland, Ohio, “catching fire” (also in 1969), and helped increase the visibility of environmental issues and create this new field of study.

Terminology
In common usage, “environmental science” and “ecology” are often used interchangeably, but technically, ecology refers only to the study of organisms and their interactions with each other as well as how they interrelate with environment. Ecology could be considered a subset of environmental science, which also could involve purely chemical or public health issues (for example) ecologists would be unlikely to study. In practice, there are considerable similarities between the work of ecologists and other environmental scientists. There is substantial overlap between ecology and environmental science with the disciplines of fisheries, forestry, and wildlife.

Atmospheric sciences

Atmospheric sciences focus on the Earth’s atmosphere, with an emphasis upon its interrelation to other systems. Atmospheric sciences can include studies of meteorology, greenhouse gas phenomena, atmospheric dispersion modeling of airborne contaminants,[4][5] sound propagation phenomena related to noise pollution, and even light pollution.

Taking the example of the global warming phenomena, physicists create computer models of atmospheric circulation and infrared radiation transmission, chemists examine the inventory of atmospheric chemicals and their reactions, biologists analyze the plant and animal contributions to carbon dioxide fluxes, and specialists such as meteorologists and oceanographers add additional breadth in understanding the atmospheric dynamics.

Thank you for this comprehensive post evaluating strategies for academic portfolios.

Like other professionals, nurses should continually pursue academic opportunities for personal and professional development. While studying and practicing in various areas, nurses should embrace opportunities that empower them through new skills, values, and perspectives. Such empowerment prepares them to positively impact individuals and communities by advancing social change. In the present communities, social change can be achieved by promoting health to ensure diverse populations live healthily.

Including academic activities in one’s professional development goals calls for multidimensional strategies. Among them, the value of inter-departmental collaboration cannot be overlooked. Essential for improved outcomes in nursing, an interprofessional approach to issues brings diverse individuals together to address a common issue. Alderwick et al. (2021) posited that this collaboration is characterized by diversity in skills, values, and principles, leading to improved understanding of issues, confidence, and innovation. Therefore, it is a crucial strategy to prepare nurses as social change agents since the advanced skills will enable them to address social issues more competently. Innovativeness also enables nursing professionals to solve problems effectively, essential for improved health outcomes in healthcare facilities and communities.

Community engagement is another valuable strategy for acquiring skills essential to social change. Pivotal in improving nursing students’ identity, community engagement is a powerful tool for nurses to advance environmental and behavioral change for improving population health (Magpantay-Monroe et al., 2020). It allows nurses to understand problematic health issues and barriers, including pollution, lifestyle, and culture. Nurses can also use community engagement opportunities to work with community-based organizations and partners supporting community health. The improved awareness of health issues at the community level enables nurses to determine effective solutions and actively participate in policy as situations necessitate.
