This is the story of Mother Nature (Madrenatur).
Madrenatur goes on vacation to relax and leaves the trees and animals as guardians of the forest. While she is gone, humans are littering the forest. When she returns, she tries by all means to clean up what man has polluted, but it is not possible and the latter ends up destroying the forest.
Madrenatur cries and then it starts to rain, and with the rain come the buds and some birds.
Madrenatur implores us to look after her.
