As a student majoring in biology, the subject of ecology is what I need badly and also what I must learn well by heart2. Although I have experienced3 only a few lectures of ecology so far, I have already smelt4 its attraction. I am convinced that it is a subject full of interesting discoveries. However, another question, forgiving me for mentioning something unpleasant5, keep striking my mind. I can't help asking myself: on the other side of the coin, with so many environmental problems like water pollution and fierce sand storm attack6 nowadays, ecology, where to go?
