"You can grow a tree in 30 years, versus your fossil fuel which takes two-or-three hundred, million years to form the carbon fuel," says Bates.
是啊，树从幼苗算起也得几十年的光景才能成材吧。
Yes ah, the tree counting from the seedlings have to be exciting for several decades to become useful bar.

When we plant a tree we do so knowing that although it will take years to grow, it will yield great benefits for future generations.
