The following diagram shows how greenhouse gases trap energy from the Sun.

The diagram illustrates the way in which greenhouse gases are produced and how solar energy is trapped by these gases Overall, the process is a cycle starting with cacbon dioxide stemming from the activities of mankind. At the first stage, the fume emitting from means of transport is one of the common elements that contributes to the earth’s atmosphere. The engine of a car, plane, motorised boat or other vehicles release toxic substances. The pollutants also meet with extra carbon dioxide, evacuated from power plants or factories which burn fossil fuels, forming a clutter of man-made pollutants. The logs trees absorbing the man-produced carbon dioxide are caused by the marring deforestation. The second stage occures in the atmosphere, where a part of the energy received from the sun is reflected back to the outer space. Instead, the greenhouse gases trap the heat, warming up the environment.
