they are watching you by nuno henriques from portugal

The main idea is this - everything we do regarding our nature, all animals are watching. Humans are the only species on Earth that cause pollution, so whatever we do on our cities regarding this, all animals will watch. Imagine that you want to throw litter on the floor, but when you look around to see if there is anyone watching you noticed that you have thousands - or millions - of animal eyes looking at you. You will think twice before doing such action.
