Impacts of Human Behavior on the Environment 2 Environmental psychology is the study of the link between human behavior, the direct impact on the environment, and the psychology of humans. The physical or manmade environment such as building houses or workplaces, and natural environments in nature, are all important parts of environmental psychology. The study that includes environmental psychology is diverse and requires more studies to determine what changes need to be made. Modern technology such as, the development of chemicals, manufacturing plants, population increases, mining and mining processes and other human activities have brought many issues and concerns about the environment. Some of the environmental issues that are impacting our environment negatively are: global warming, climate changes, more intense adverse weather such as stronger hurricanes and tornadoes, while other areas have drought and rainy conditions (Steg, 2013). Technology can create negative impacts to the environment by humans attempting to improve on nature in areas where nature should be left alone. Controlling nature, for example, by building dams over rivers to generate electricity has adverse effects on fish and other water species. The oil and chemicals that are used to maintain the electricity generating turbines often leak and can pollute the river that is being used to the manmade purpose. Some species of fish can no longer swim to instinctual spawning grounds causing the loss of many fish. Agricultural practices are necessary to provide food sources for people and to help prevent starvation. However, certain agricultural activities such as spraying chemicals can cause water pollution. The chemicals run off the plants into the ground and into water sources. The chemicals can cause illnesses and death for other plant, animal, insect and human life. Agriculture has Impacts of Human Behavior on the Environment 3 proven to have significant changes on the climate. The greenhouse effect produces and releases carbon dioxide, methane and nitrous oxide, which can change the earth’s ability to either absorb or reflect heat and light. The greenhouse effect appears to be altering the climate of earth causing warmer than usual temperatures, which also is causing a dramatic change in weather cycles. The weather changes can have negative impact on humans when more storms and destruction take place. The deforestation and desertification together with the use of fossil fuels have created carbon dioxide, which is affecting the ozone layer and the overall health of the environment. The development of massive corn fields has altered the temperature of earth and created warmer and more humid areas, which alters the atmosphere (Wiley & Sons, 2013). Many agricultural areas use fertilizer that is inorganic and they use pesticides that kill many insects that help maintain a healthy ecosystem. The impact of the pesticides is more impactful than most people who use them realize. More than 98 percent of pesticides harm areas other than the intended target, including water systems, food sources, and polluting air. The environment is impacted in areas of fishing by over fishing and positively by use of fishing hatcheries. The fishing hatcheries grow and release fish into depleted waters which helps fish recover from over fishing. Mining impacts the environment by contaminating groundwater from chemicals, creating sinkholes and contaminating soil. Logging can leave behind debris that disturbs the natural balance of an ecosystem and cause top soil to blow away in the wind and become unavailable. In many places logging is done in forested areas to make room for...
