They exist long before us!

The plants, they exist on this planet long before the first human walk among them. They are here long before any living organism. That’s the reason when you examine the DNA of rice plant, it resembles with human DNA more than 70%.

When ever you cut a tree without any reason, you kill a living creature like you and in the same way if you plant a tree you make a life. It’s up to you whether to take or give a life. Your little effort towards this planet to make it green will echoes to the centuries and heard long after you had gone. The planet will always thanks you and give a beautiful atmosphere to your generation and their generations.
