The greenhouse effect is a process that occurs when energy from the sun goes through our planet's atmosphere and warms the planet's surface. These heat-trapping gasses can be thought of as a blanket wrapped around Earth to insulate the surface of the earth and prevent it from freezing and making the survival of living beings on earth possible. It is also one of the most serious problems that we’ve encountered because the extra greenhouse gasses in our atmosphere cause our planet to warm up. It results from our modern lifestyle and relates to action by humans: the excessive use of automobiles, air conditioning and fridges cause an increase of greenhouse gasses in the atmosphere.
One of the common problems in this area, attributable to weather conditions, is the foggy weather in winter. For quite a few days, the fog can be so thick that the expressways and airports have to be closed to traffic, which can result in great economic loss. Another problem that comes into my mind is rheumatoid arthritis which many senior people suffer from due to the humidity, especially in summer.
With the greenhouse effect, people can sometimes see snow in Fansipan, the highest peak in Vietnam, in winter. In summer, it is very difficult for the elderly and children to tear themselves away from air conditioned rooms
