Thanks jaggi,
These are very nice pictures, i also like lush green gardens. I will taken pictures of my planted trees and share those to you.
In my knowledge, nothing in this world that can efficiently convert light energy into useful products except green leafs.
Furthermore light falls on the earth surface is converted into heat energy and helps in increasing temperature. This is the main cause of increase in earth temperature. (Energy can neither be created, nor be destroyed but it convert from one form to another form).
So it is our choice to convert light energy into useful product or heat....
