Biology is a very, very broad field; it's generally defined as 'the science of life', but you already know that.
The question on my mind is: who is a biologist? The question may seem very simple at first: well of course a biologist is someone who studies biology. But in truth it's not that simple.
Would you, for example, call a doctor a biologist? Of course such a person is involved in the 'science of life'; he/she studies life, and even fights to preserve it.
Many of us see biologists as researchers: people who study the ecosystem, or seek cures to and prevention of diseases. But is this the right view? Why don't we view doctors as biologists?
