Although our modern civilization has had many negative effects on the environment, we recognize that modern civilization has also made the environment more livable in many ways. With medical and technical advances, we are having better health care. Average life expectancy is increasing. We are protecting ourselves better from natural hazards, such as earthquakes, hurricanes, and tornadoes. We are feeding more people, and feeding them better than ever before. In the past few years, we have begun to learn how we can use our technologies to live in close harmony with our environment than we have im the recent past. For example, we are attempting to control some pests using better methods than were used earlier, in the twentieth century. We are experimenting with new ways of growing crops.
