Accumulation of waste in Hyrcanian forests endangers not only the health of the forest but also its inhabitants. Accumulations of heavy metals such as copper, zinc, cadmium and lead enter the soil and aquifers and penetrate into bodies of animals and humans. Accumulated gases such as methane also cause forest fires.

Skin- Bark shows the relationship between the bark of hyrcanian trees and the skin of different parts of the body. Our growth and development are intertwined, and our recklessness will destroy this glorious heritage.
