The leaf is always associated with nature. Most plants feed through leaves. But the first association with the word brings trees to mind. It is their size in relation to the human dimension that makes the crowns of trees full of leaves build the landscape that surrounds us. In spring, when a bud appears on its branches from which a leaf develops, they bring us the hope of waking life. Their greenery is then very intense and fresh. In summer, we treat the presence of greenery as something natural that belongs to this time of year. The most interesting spectacle begins in autumn when the trees are getting ready for winter sleep. That’s when the leaves fall from the trees and form multi-coloured carpets on the ground. Then they take on a variety of colours. They want to enchant us with their beauty before they die. This is how nature tells us about the cycle of life and death through leaves. Cycles in nature determine the rhythm of life and death. Nature inspires us with its diversity and beauty. However, we find it difficult to accept that death is part of it. The death of plants does not hurt as much as the death of animals or the passing away of humans. We do not communicate with plants as we do with other living beings. That is why autumn leaves are a natural signal to us of another autumn in our lives. We do not associate colourful dry leaves with death. Quite simply, this is how plants prepare for winter.
