Although the article is about very serious topics, such as global warming and species extinction, it also highlights a very happy phenomenon: serendipity. Serendipity occurs when you are looking for one thing but find something else, something that is perhaps more valuable or interesting than what you were originally looking for. For example, consider the story of Alexander Fleming, a renowned researcher who was investigating how the staphylococcus bacteria behaved. One day, he came back to his laboratory and found that some fungus had entered one of the containers of staphylococcus bacteria he was using in his experiments. Instead of just throwing away the contaminated sample, he took a close look at it, and noticed that the staphylococcus bacteria around the fungus had been killed. Intrigued by the bacteria-killing property of this mysterious fungus, Fleming quickly changed his research focus. The fungus he discovered, penicillin, is still one of the most effective medicines we have for battling infection. Yes, it would be easy to dismiss a discovery like that as being due to luck or blind chance. But a good researcher creates an atmosphere where luck can happen. If you keep your eyes and mind open, serendipity may well pay you a valuable visit too!
