Summary

In recent years, we can see the eco-friendly buildings called "green buildings". There are several examples of the "green buildings" around the world. There are big windows which is controled to turn off the lights to reduce the use of electric lights. Also, solar cells on the roof convert sunlight into electricity. The buildings have gardens on the roof thesedays. It means people make a garden on the building's roof to keep heat inside the builing from escaping.(esp. in winter of course) Additionally, to solve the drought problem.

Comment

Nowadays, as I mentioned above, there are lots of green friendly buildings appearing. Many scientists and naturalists are creating new technologies to make the world better place to live. However, I believe that these new ways to save the environment are useless without any efforts of nations (citizens) to save our mother earth. Therefore I urge all of the human races to do your best to protect the natural environment.
