Quote: Ramsar Convention Secretariat, 2007. Laws and institutions: Reviewing laws and institutions to promote the conservation and wise use of wetlands. Ramsar handbooks for the wise use of wetlands, 3rd edition, vol. 3. Ramsar Convention Secretariat, Gland, Switzerland.
Processes which modify the natural properties of wetlands may be broadly grouped into four categories:
a) loss or degradation of wetland area and landscape;
b) changes in the water regime (e.g., velocity, volume, seasonal flows, groundwater);
c) changes in water quality (e.g., pollution, eutrophication, sedimentation); and
d) overexploitation or disturbance of wetlands and wetland products.
Processes of this kind are generated by human activities both inside and outside wetlands. Some types of human activity (e.g., drainage, pollution or urban encroachment) almost always generate processes damaging to wetlands, whether individually or on a cumulative basis. Other types of activity (e.g., fishing, agriculture or ecotourism) may be consistent with wise use within certain limits, but can generate damaging processes if they exceed the carrying capacity of the water system, coastal zone or wetland concerned.
作為Ramsar Convention之一的中國，我地的正苦似乎未有根據指引去管理和善用濕地，任由發展商在國際重要濕地的範圍內，興建十多層高的住宅（urban encroachment)，更沒有用宏觀的角度，檢視一個接一個的發展所帶來的負面影響(cumulative basis)，而即使所謂的保育管理，其實都有一定的上限(certain limits)。
大商家在正苦的默許下，正不斷吸乾我們國際重要濕地，而環團亦似乎被他們用壓榨的手段，續步陰乾，最終，沒了濕地，沒了反對聲音，大西北更能與祖國接軌。
