Click here to see an interesting article on taxonomy by CAROL KAESUK YOON.
I like the last paragraph, copied below, which shows the value of the profession.
Just find an organism, any organism, small, large, gaudy, subtle — anywhere, and they are everywhere — and get a sense of it, its shape, color, size, feel, smell, sound. Give a nod to Professor Franclemont and meditate, luxuriate in its beetle-ness, its daffodility. Then find a name for it. Learn science’s name, one of countless folk names, or make up your own. To do so is to change everything, including yourself. Because once you start noticing organisms, once you have a name for particular beasts, birds and flowers, you can’t help seeing life and the order in it, just where it has always been, all around you.
