The Earth’s environment is under increasing pressure from human activities. From climate change and pollution to deforestation and resource depletion, the challenges are complex and far-reaching. Understanding these issues and developing solutions requires a multifaceted approach, and this is where environmental science comes into play.
But What Is Environmental Science exactly? In simple terms, it’s the study of the environment and our relationship with it. It’s a field dedicated to understanding the intricate workings of the natural world and how we, as humans, interact with and impact it. As Senator Gaylord Nelson, a prominent environmental activist, wisely stated in 1980, a decade after the first Earth Day, “proper management of its resources will be the most fundamental issue we face. Our very survival will depend on whether or not we are able to preserve, protect and defend our environment.” His words resonate even more strongly today, highlighting the critical role of environmental science in ensuring a sustainable future.
Defining Environmental Science: An Interdisciplinary Approach
To delve deeper into what environmental science is, it’s crucial to recognize its interdisciplinary nature. As Jill Nugent, a science instructor at Southern New Hampshire University (SNHU) and a contributor to the National Science Teaching Association (NSTA), explains, “Environmental science is an interdisciplinary field that integrates scientific methods and disciplines to understand and address real-world environmental challenges.”
This means environmental science isn’t confined to a single area of study. Instead, it draws upon a diverse range of disciplines to provide a holistic understanding of environmental issues. These key disciplines include:
- Earth Sciences: Examining the physical constitution of the Earth, including geology, soil science, and hydrology, to understand natural processes and resource management.
- Life Sciences: Incorporating biology, ecology, and zoology to study living organisms and their interactions within ecosystems.
- Physical Sciences: Applying chemistry, physics, and atmospheric science to analyze environmental processes and pollution.
- Social Sciences: Integrating economics, sociology, and political science to understand the human dimensions of environmental problems and develop effective policies and solutions.

By bringing together these diverse perspectives, environmental science provides a comprehensive framework for analyzing complex environmental problems and crafting informed, effective solutions. For individuals passionate about making a positive impact on the planet, environmental science offers a powerful and versatile field of study.
The Importance of Environmental Science in Today’s World
The significance of environmental science has never been greater. Dr. Kelly Thrippleton-Hunter, an adjunct instructor at SNHU and a health risk assessor for the New Hampshire Department of Environmental Services, emphasizes this point: “The focus of environmental science is to learn how the natural world works, understand how we interact with our natural world, and determine how we can address environmental issues to preserve that natural world around us.”

Understanding the intricate relationship between human activities and the environment is paramount for several reasons:
- Addressing Environmental Problems: Environmental science provides the knowledge and tools necessary to identify, analyze, and address critical environmental issues like pollution, climate change, biodiversity loss, and resource depletion.
- Sustainable Solutions: By understanding ecological principles and human impacts, environmental scientists can develop sustainable practices and policies that minimize harm to the environment while meeting human needs.
- Protecting Ecosystems and Human Health: A healthy environment is essential for both ecological balance and human well-being. Environmental science plays a crucial role in protecting ecosystems, ensuring clean air and water, and mitigating environmental health risks.
- Informing Policy and Decision-Making: Environmental science research provides crucial data and insights that inform environmental regulations, policies, and conservation efforts at local, national, and global levels.
The establishment of the Environmental Protection Agency (EPA) in 1970 marked a significant milestone in recognizing the importance of environmental protection. Landmark legislation like the Clean Air Act and Clean Water Act, driven by scientific understanding, has had a profound positive impact on environmental quality. However, ongoing research and education in environmental science remain vital to address existing challenges, prevent future damage, and ensure a healthy planet for generations to come. As Jill Nugent aptly points out, “Environmental science is important to all of us because we have no ‘Planet B’ to inhabit.”
Environmental Science Careers: A Wide Spectrum of Opportunities
One of the compelling aspects of environmental science is the breadth of career paths it offers. Dr. Thrippleton-Hunter highlights the versatility of an environmental science degree: “An environmental science degree is so versatile that the sky would be the limit to what someone could do with it.”
While the title “environmental scientist” is a prominent career option, the field encompasses a diverse range of roles across various sectors. Some key environmental science careers include:
- Environmental Scientist/Specialist: Conducting research, analyzing environmental problems, developing solutions, and ensuring regulatory compliance. This can involve fieldwork, data analysis, report writing, and collaboration with various stakeholders.
- Environmental Consultant: Advising businesses, government agencies, and organizations on environmental issues, sustainability practices, and regulatory compliance. Consultants often conduct environmental assessments, develop management plans, and assist with permitting processes.
- Sustainability Manager: Developing and implementing sustainability initiatives within organizations, focusing on reducing environmental impact, improving resource efficiency, and promoting corporate social responsibility.
- Environmental Planner: Working on urban and regional planning projects, integrating environmental considerations into land use planning, transportation, and infrastructure development.
- Landscape Architect: Designing sustainable and aesthetically pleasing outdoor spaces, incorporating ecological principles and promoting environmental conservation.
- Environmental Health Specialist: Focusing on the relationship between environmental factors and human health, working to identify and mitigate environmental hazards that impact public health.
- Environmental Educator: Teaching and raising awareness about environmental issues in schools, universities, nature centers, museums, and communities.
- Policy Analyst: Analyzing environmental policies, conducting research, and advising policymakers on environmental regulations and legislation.
- Conservation Scientist/Park Ranger: Managing natural resources, protecting ecosystems, and educating the public in parks, wildlife refuges, and conservation areas.
These are just a few examples, and the possibilities continue to expand as environmental awareness grows and new challenges emerge. Careers in environmental science can be found in various sectors:
- Government Agencies: Federal, state, and local agencies like the EPA, National Park Service, and state environmental departments employ environmental scientists in diverse roles.
- Private Sector: Businesses in various industries, including consulting, energy, manufacturing, and agriculture, need environmental professionals for sustainability, compliance, and risk management.
- Non-profit Organizations: Environmental advocacy groups, conservation organizations, and research institutions offer opportunities to contribute to environmental protection and research.
- Education: Universities, colleges, and schools need environmental science educators and researchers.
According to the U.S. Bureau of Labor Statistics (BLS), the job outlook for environmental scientists and specialists is projected to grow faster than average. The median annual salary for these roles in 2022 was $76,480, reflecting the increasing demand and value of environmental expertise.
Why Study Environmental Science? The Benefits of an Environmental Science Degree
Choosing to study environmental science offers numerous personal and professional benefits. As Jill Nugent explains, environmental education is about “engaging individuals, organizations, and communities to learn more about the environment by both informing them and inspiring them to act.” An environmental science degree equips individuals with the knowledge, skills, and passion to become effective environmental stewards.
