Why does the poet call the sight a tragic sight in the poem 'Heritage of Trees'?

The poet calls the sight a tragic sight in "Heritage of Trees" because they are witnessing the destruction of the old trees that hold historical and cultural significance. The loss of these trees represents the breaking of a connection to the past and the inability to preserve tradition for future generations. This loss is deeply saddening, thus the poet uses the term "tragic" to convey the emotional impact of this destruction.
