Leaf is a one key to think about “Circular Economy”

:

Hi, it’s been a while since our last post here.

Today, I think about the “Leaf” a little.

:

We can’t make even one leaf. 

Their structure and system are amazing. 

Leaf can make nutrients to grow by themselves. 

Leaf can pump water up to each cells from the ground without any energy. 

Leaf can be nutrients for other plants and animals. 

So, Leaf is great one piece of circular system of nature while having impressive structure.

Maybe, we can learn from this, and make human society more sustainable.
