Switch from mechanical engineering to environmental engineering

I started off my freshman year as a Mechanical Engineer student. Now i am in Sophomore year and i am having a big confusion whether the major i selected was right or not? I am having big second thoughts whether the major i selected is right for me or not. Right now i am having a interest in Chemical and Environmental engineering and must admit that i am good in chemistry and have good understanding and enthusiasm in working for environment. Could you please help me clear my doubts. Can you please explain me the variation of these three fields, the type of job i will be doing for these different engineering when i graduate.

Since I'm a mechanical engineer, it would be great if you stayed with mechanical. On the other hand, it sounds like you need to explore environmental engineering and chemical engineering to see if you would like one of those better.  I don't know much about jobs in chem eng or env eng.  In mechanical engineering, there is a wide variety of jobs.  Many jobs involve design and manufacturing of consumer products, but there are lots of other possibilities too. You might check out some of the senior design projects in the different majors in your school.  That will give you an idea of the type of work the various types of engineers do.  If you have the time, take a chem eng or env eng class to check it out.   Good luck.
