In the world every where we humans destroy forests and plants to make that place for their own use... Many buildings are built where long ago it was full of forests and animals.
Due to this type of works now we can see the climate conditions are changing and the scientists are struggling to predict weather changes such as; cyclone, tsunami and earthquakes.
Anything can happen and we could not prevent nature when it's harsh and destroys everything we made...

On the other side we mainly depend on plants and trees for our livelihood. So we should try our level best to plant more trees and plants to save the nature. Greenhouses is a variety of glass house used to develop the growth of plants at very cool circumstances. Plants need sunlight to grow well. In hill stations we mostly will have cool climate conditions. On that places a green house is created for the growth of plants which normally grow under sunlight. Plastic and glasses are used to make a green house. It may be small in size or a little bigger according to the need of that place. In greenhouse the sunlight radiation directly passes through the glass and reaches the plants inside it.

After that plants also re-radiated some energy in the form of infra red rays. It is also absorbed by the glasses and sent again to the air. So air inside the green house also remains warm and provides the necessary elements for plants to grow well It also protects the plants from over heated and gets destroyed. This is the most useful method and provides food for all people in the tough climate conditions. If we do not have a method like this then we could not able to live in hard climate conditions. The cost for making green houses are also low. In countries like Netherlands they mainly use greenhouse method to produce vegetables for their livelihood. This can be said as one of the great revolution in the history of agriculture field.
