The extinction of many species of birds has undoubtedly been hastened by modern man; since 1600 it has been estimated that approximately 100 bird species have become extinct over the world. In North America, the first species known to be annihilated was the great auk, a flightless bird that served as an easy source of food and bait for Atlantic fishermen through the beginning of the nineteenth century. Shortly after the great auk's extinction, two other North American species, the Carolina parakeet and the passenger pigeon, began dwindling noticeably in numbers. The last Carolina parakeet and the last passenger pigeon in captivity both died in September 1914. In addition to these extinct species, several others such as the bald eagle, the peregrine falcon, and the California condor are today recognized as endangered; steps are being taken to prevent their extinction.

Manic depression is another psychiatric illness that mainly affects the mood. A patient suffering from this disease will alternate between periods of manic excitement and extreme depression, with or without relatively normal periods in between. The changes in mood suffered by a manic-depressive patient go far beyond the day-to-day mood changes experienced by the general population. In the period of manic excitement, the mood elevation can become so intense that it can result in extended insomnia, extreme irritability, and heightened aggressiveness. In the period of depression, which may last for several weeks or months, a patient experiences feelings of general fatigue, uselessness, and hopelessness, and, in serious cases, may contemplate suicide.
