Environmental science is a broad discipline that encompasses many different fields. It can be broken down into four main areas:
1. Ecology
2. Geography
3. Meteorology
4. Chemistry

If you're planning on attending graduate school, you might want to think about getting student loans. This way, you won't have to worry about paying back any money until you start making a decent income. Student loans are available from private lenders, banks, and government agencies. Private lenders charge higher interest rates than banks do. Government-backed loans tend to carry lower interest rates than private loans. It's important to compare loan options carefully before deciding what type to apply.
If you plan on going to graduate school, you'll probably need to get some financial aid. Financial aid comes in many forms, including grants, scholarships, and federal loans. Grants and scholarships are given directly to students without requiring repayment. Federal loans require repayment but don't have to be immediately paid back. They can be used to pay for tuition, fees, room and board, books, supplies, and other expenses related to your studies.

The United States Environmental Protection Agency (EPA) defines environmental science as "the scientific knowledge base needed to understand human activities and their effects on the environment." In addition, EPA states that it is "a multidisciplinary profession that uses science to protect human health and improve the quality of life by reducing risks associated with exposure to chemicals, radiation, and other agents found in the environment."
To become an environmental scientist, you must complete at least three years of college or university before entering graduate school. It would help if you also had a strong interest in the subject. Many students enter graduate programs after earning a bachelor's degree in environmental science. However, those who want to pursue a career in environmental science may find earning a master's degree easier. Some universities offer certificates in environmental science. These courses focus on specific aspects of the field. For example, there are certificate programs in environmental law, environmental education, and environmental technology.
Students interested in pursuing a career in environmental science must consider several factors when choosing a program:
They should ensure that the program offers a curriculum to prepare them for a job in this field.
They should look for accredited programs that meet national standards.
They should take advantage of internships and practicums offered by the program.

Students interested in becoming environmental scientists should begin by taking classes in high school. High school teachers teach these subjects but may not know much about the field. If your teacher does not cover the material well enough, ask them if they know anyone who works in the field. You can also check out books written by professionals in the field.
Once you've decided which coursework you'd like to pursue, you'll need to choose a major. Biology, chemistry, physics, geology, meteorology, and ecology are the most popular majors. Each of these fields has different requirements for admission into graduate schools. Students interested in studying environmental science should know the differences between each field to decide which one best suits their interests.
