These environmental guardians work in labs and out in the field helping scientists as they test air, soil, and public spaces to check for pollution and other not-so-fun issues. In this job, which is ideal if you want to avoid office work, you might tackle tasks such as setting up equipment to monitor the emissions from smokestacks, testing soil samples, and walking through buildings to confirm that no health hazards (like asbestos) are lurking. If you decide on this career you could end up traveling to different locations to meet with clients, whether that means investigating a chemical spill at a manufacturing plant, touring an amusement park for an inspection, or checking the water quality of a river. You'll come home from work each night knowing that your job not only keeps others safe, it also helps protect the planet. Who can argue with that?
