Biotechnology is a vast topic to cover in a few sentences. It mostly deals with genetics and molecular and cellular and nuclear level of practical studies of living cells. It is one of the most sought after career and if you are lucky enough, you can earn a lot but then again you have to work hard and study a lot.

It totally depends upon your interest. If you are interested into the subject you must go for it. It's always better to do what you want to do than what others want you to do. Go through the subject topics and also know about other streams also go through its topics, BT has wide scope into science researches, so if you feel pull towards it, go ahead.
All the best! :)
