Have you ever noticed that for people with asthma it can sometimes be especially hard to breathe in the middle of a busy city? One reason for this is the exhaust from vehicles. Cars, buses, and motorcycles add pollution to our air, which affects our health. But can pollution impact more than our health? Cutting down trees, or deforestation, can contribute to erosion, which carries off valuable topsoil. But can erosion alter more than the condition of the soil? How does an oil spill harm fish and aquatic plants? How does a population of animals interact with its environment? These are questions that environmental scientists study and try to find answers to. They conduct research or perform investigations to identify and eliminate the sources of pollution or hazards that damage either the environment or human and animal health. Environmental scientists are the stewards of our environment and are committed to keeping it safe for future generations.Do You Have the Skills and Characteristics of an Environmental Scientist?

Typical degree for an entry-level position: Bachelor's degree ?
A bachelor's degree in an earth science is adequate for entry-level positions, although many companies prefer to hire environmental scientists with a master's degree in environmental science or a related natural science. A doctoral degree generally is necessary only for college teaching and some research positions. Some environmental scientists and specialists have a degree in environmental science, but many earn degrees in biology, chemistry, physics, or the geosciences and then apply their education to the study of the environment. They often need research or work experience related to environmental science.
A bachelor's degree in environmental science offers an interdisciplinary approach to the natural sciences, with an emphasis on biology, chemistry, and geology. Undergraduate environmental science majors typically focus on data analysis and physical geography, which are particularly useful in studying pollution abatement, water resources, or ecosystem protection, restoration, and management. Understanding the geochemistry of inorganic compounds is becoming increasingly important in developing remediation goals. Students interested in working in the environmental or regulatory fields, either in environmental consulting firms or for federal or state governments, should take courses in hydrology, hazardous-waste management, environmental legislation, chemistry, fluid mechanics, and geologic logging, which is the gathering of geologic data. An understanding of environmental regulations and government permit issues also is valuable.
For environmental scientists and specialists who consult, courses in business, finance, marketing, or economics may be useful. In addition, combining environmental science training with other disciplines such as engineering or business qualifies these scientists for the widest range of jobs.
Companies That Hire Environmental Scientists
Try it Out with an Activity or Project
STEM Activities
STEM activities are fun hands-on explorations that usually take from 10 minutes to one hour and use readily available household or classroom materials while introducing you to STEM concepts common in this career.
Science Project Ideas
Project Ideas are in-depth STEM explorations that have a strong focus on controlling variables, taking accurate measurements, and analyzing data suitable for investigating the scientific method or the engineering design process.
On the Job
Role Models
Nature of the Work
Environmental scientists use their knowledge of the natural sciences to protect the environment by identifying problems and finding solutions that minimize hazards to the health of the environment and the population. They analyze measurements or observations of air, food, water, and soil to determine ways to clean and preserve the environment. Understanding the issues involved in protecting the environment—degradation, conservation, recycling, and replenishment—is central to the work of environmental scientists. They often use this understanding to design and monitor waste disposal sites, preserve water supplies, and reclaim contaminated land and water. They also draft risk assessments, describing the likely effect of construction and other environmental changes, write technical proposals, and give presentations to managers and regulators.
Many environmental scientists work for local, state, and federal governments, ensuring that environmental regulations are followed to limit the impact of human activity on the environment. Others monitor environmental impacts on the health of the population, checking for risks of disease and providing information about health hazards. Environmental scientists also work with private companies to help them comply with environmental regulations and policies. They are usually hired by consulting firms to solve problems.
Many environmental scientists have jobs and training similar to other physical or life scientists, but they focus on environmental issues. Many specialize in subfields such as environmental ecology and conservation, environmental chemistry, environmental biology, or fisheries science. Specialties affect the specific activities that environmental scientists perform, although recent understandings of the interconnectedness of life processes have blurred some traditional classifications. For example, environmental ecologists study the relationships between organisms and their environments and the effects on both by factors such as population size, pollutants, rainfall, temperature, and altitude. They may collect, study, and report data on air, soil, and water using their knowledge of various scientific disciplines. Ecological modelers study ecosystems, pollution control, and resource management using mathematical modeling, systems analysis, thermodynamics, and computer techniques. Environmental chemists study the toxicity of various chemicals—that is, how those chemicals harm plants, animals, and people.
Work Environment
Many entry-level environmental scientists and specialists spend a significant amount of time in the field, while experienced workers generally devote more time to office or laboratory work. Some environmental scientists, such as environmental ecologists and environmental chemists, often take field trips that involve physical activity. Environmental scientists in the field may work in warm or cold climates, in all kinds of weather. Travel often is required to meet with prospective clients.
