The greenhouse effect is a natural system that regulates the temperatures on Earth by trapping the sun 's heat to keep the temperature on the surface warm enough to support life. However, increasing levels of the greenhouse gases as a result of industrialization and rising population continue to increase the temperatures on the Earth 's surface causing various physical, environmental, climatic and ecological changes on
