Actually it means a lot. My degree is in science and I've studied biology and many other fields extensively. Biology is indeed the study of life. Without biology how would doctors know about our bodies and how it works? Without biology vets wouldn't know about your pet's body and how to heal it. Sure these Physicians go deeper than biology or zoology, but without learning the basics of biology first they would be doomed to fail.
Put all that aside and just pure knowledge makes studying biology important. Knowing how cells work, how neurons and synapses work is amazing information. I don't know about you but my brain is a sponge. I take in all the information I can gather.
Science is very interesting-Be it chemistry, botany, biology, zoology, genetics, biochemistry, or medicine. All of them are important! Every feild of science brings about information that helps us understand the circle of life.
Would you really want a surgeon to cut on your that never studied biolgoy or knew how the human body works at a cellular level?
All areas of biology or science is important.
