Other man-made causes of the increase in the greenhouse effect is the emission of greenhouse gases by electrical appliances. These gases, chlorofluorocarbons (CFCs), are used on a large scale in the electronic industry. Some processes of the cement manufacturing industries also act as a cause towards the greenhouse effect. Population growth is an indirect contributor and one of the major causes of the greenhouse effect. With the increase in population, the needs and wants of people increase which consequently increases deforestation, manufacturing, and industry processes.
