Winter comes, you wish it was summer.

"Scientists have long wondered if the red color of fall leaves was more than just a sign of death. The molecules behind bright yellows and oranges are well understood, but brilliant reds remain a bit of a mystery.The yellow color has been there all summer, but you don't see it until the green fades away.

The red pigments serve as antifreeze, protecting cells from easily freezing. But red leaves are also signal of distress. If you see leaves of a tree turning red early, in late August, the tree is most likely suffering from a fungus or perhaps a ding from a reckless driver”


Livescience




Summer, summer
well,
might had died long ago before the first leaf started to fall.
