Most consumers do not understand either the PCF statement or the PCF calculation. The public message of a PCF label does not conform to the terms of sustainability. At first sight, PCF seems to be an opportunity to communicate the sustainability aspects of food to consumers, but too many different approaches to defining PCF exist in Europe. Additionally, the use of a ＂green＂ PCF label may distort trading conditions because of the lack of PCF-issuing authorities in accordance with World Trade Organization （WTO） standards. Hence, PCF may ultimately deceive consumers through its misapplication if the PCF calculation is not aligned to internationally accepted standards.展开更多

Knowledge of the potential significance of trees in urban landscapesis expanding rapidly as research continues to document the important role that urban forests and trees canplay in improving the quality of urban life. The environmental conditions in urban landscapes are, however,very different from the natural conditions that the tree species are adapted to. This poses big challenges tothe urban forestry in its efforts to create healthy and valuable trees in urban landscapes. Only throughimplementing some important measures we can ensure high survival rate of saplings and well-being andlongevity of urban trees.展开更多
