A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.[1] These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external ambient temperature, protecting its contents in cold weather.
Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables or flowers. The glass greenhouses are filled with equipment including screening installations, heating, cooling, lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to evaluate optimality-degrees and comfort ratio of greenhouse micro-climate (i.e., air temperature, relative humidity and vapor pressure deficit) in order to reduce production risk prior to cultivation of a specific crop.

Answer
The word green house comes from the house which was used early in cold countries for seed germination as in cold countries the amount of sunlight is not enough for seed germination.
Green house effect is the entering of solar radiation to pass in but prevent long wave heat radiation to pass out due to presence of solar gases. These gases allow the solar radiation to pass through but reflect back the long wave radiations back to earth , are called green house effect.
Carbon dioxide , chroro - floro carbon and nitrogen oxide are green house gases which are mostly produced by industries ,factories and by automobile's exhaust.
Due to green house effect the temperature of the surface of earth , on its immediate atmosphere rises and this phenomenon is called global warming.
Global warming leads to melting of glaciers , occurence of diseases , adverse effect on plant yields.
So we need to reduce the use of automobiles and we should stop deforestation and start afforestation.
Save green , Go green
