This page contains information on environmental science-related professions, details on environmental science online degree programs, and steps for finding a program that meets your academic and career goals.

What Is Environmental Science?

Environmental science is an interdisciplinary field that comprises the natural sciences. Highly trained environmental scientists play a vital role in informing the public and policymakers about how people's actions (e.g., consumption and pollution) affect the environment and human health. In the 20th century, the important work of these professionals led to the creation of the U.S. Environmental Protection Agency (EPA). Since its inception in 1970, the EPA has pushed for better fuel efficiency standards and regulations on disposing of industrial waste, among other initiatives.

Many leading environmental scientists possess both a basic understanding of the field's different disciplines and expertise in one subfield. This allows them to collaborate with peers from other scientific backgrounds. Advancement opportunities are usually greater for environmental scientists with a master's or doctoral degree. The best environmental science bachelor's degree online programs can provide you with an excellent academic foundation for career entry and further academic studies.

Expert Interview

Why did you choose to earn a degree in environmental science? Is this a field that always interested you?

Ironically enough, environmental science was not my first choice for a degree. Instead, I stumbled across it inadvertently as a marine biology major during the second semester of my freshman year. While registering for classes, I noticed some available courses that piqued my interest but were primarily for environmental science majors. At that point, I did some research and realized I could reasonably become a double major while still graduating at the same time, since many core classes required by both majors overlapped.

Although there were various factors involved in adding environmental science as my second major, the primary reason was because I had always been interested in the field. As a relatively new college student still at that time, I did not know what my post-college future would look like, and I also wanted to enter the job market as a versatile candidate in order to see where I truly would fit in.

What was the job search like after completing your bachelor's degree?

My job search started during my senior year and, as many people experience, I had absolutely no idea what type of job I wanted. As a result, as I applied to various positions, ranging from lab work to educational efforts to fieldwork, and even some worst-case-scenario, fall-back options that were completely unrelated to either of my majors. As the application and interview processes developed, I began to have a better understanding of where I could see myself working, which was not in a typical 9-5 office job. So, through the course of the process, I began to adjust my searches, all while still trying to not be too picky.

If I had to describe my job search experience in one word, it would be "daunting." Knowing that I was applying and essentially competing for a position that so many other, potentially more qualified people were also applying for was very daunting. Knowing that I had to have the "right" answers during an interview so as to not ruin my chances of an opportunity -- daunting. Looking back is interesting (like many things in life), as all of those daunting choices I made then have led me to where I am now.

What jobs have you had in the environmental science field? Which did you prefer the most, and why?

I have technically held two distinct roles, both through the nation's largest lake management company, SOLitude Lake Management. I started as an aquatic biologist and have since transitioned into a regional manager position. As I fulfill both roles concurrently each day, it's hard to say which I prefer the most, as it truly is one fluid position to me.

No two days are ever the same in my position. I enjoy serving our clients and designing lake and pond management programs that restore balance to their aquatic resources. Likewise, in my leadership role, I enjoy helping my own scientific team grow, both professionally and personally, which continually motivates me to do the same.

What are some crucial skills that you acquired through your bachelor's program?

Aside from the true fundamentals of environmental science and biology, the most important skill I learned through my undergraduate education was time management. In an employment setting, procrastination is not sufficient nor appropriate, as colleagues and clients are often depending on the timely, high-quality completion of a task in order to reach their goals.

What are some of the challenges you face in your work on a day-to-day basis?

It can be challenging to work in a primarily male-dominated industry, and this seems to be the case for various science fields. However, the industry is absolutely changing; just over the last few years, I've noticed an overall shift of women becoming more involved in the aquatic management industry, and it's incredibly exciting.

A challenge a bit more specific to my scientific role is ensuring the public and our clients are effectively educated on best management practices for the environment, new technology, and sustainable lake management strategies. Unless they live on a lake or pond, many people are generally unaware that my industry even exists, resulting in incomplete perceptions of what I do.

What are some of the most rewarding aspects of your career in environmental science?

One of the most rewarding aspects of my job is utilizing my knowledge and experience to help clients improve the health, beauty, and functionality of the aquatic resources on their properties. I get fulfillment from knowing that their questions and concerns have been addressed. It is incredibly satisfying to help someone learn more about lake management and to provide valuable information that they will hopefully pass along to others.

Another rewarding aspect of my job is managing an environmental project over the course of a year (or more) and quite literally witnessing the ecological transformation. I oversee projects from start to finish, inclusive of management implementation, which allows me to observe the success and/or areas I may need to adjust for those projects on a yearly basis. Hand in hand with many success cases, the subsequent client satisfaction and happiness is also incredibly rewarding.

What advice would you give to students who are considering a bachelor's degree in environmental science?

Do not be afraid to stick it out and to find your passion. It definitely will not be easy, for various reasons, but it is absolutely worth it in the end. In college, I used to joke that I just wanted to work on a boat -- that's exactly what I'm doing now. To any student who is certain about choosing environmental science as a major but uncertain what specific field to pursue beyond college, I highly recommend thinking of the related environmental aspects they may be passionate about and following those. Opportunities are everywhere.
