3-7-4We Need to Learn More about the Health of the World's Ecosystems

We need baseline data on the condition of world's ecosystems to see how they are changing and to develop effective strategies for preventing or slowing their degradation.
我們需要基準數據來觀測世界上的生態系統是如何變化，並做出有效的對策來防止它的退化與減緩。


By analogy,your doctor needs baseline data on your blood pressure,weight,and functioning of your organs and other systems,as revealed through basic tests.
If your health declines in some way,the doctor can run new tests and compare the results with the baseline data to identify changes and come up with a treatment.
就像你的醫生需要用以一些檢驗來獲得血壓、體重、及身體器官的運作狀況這些基準數據。
如果你的健康狀況出了問題，醫生可以藉由新的檢驗與基準數據比較差異來變更治療方式。


According to a 2002 ecological study published by the Heinz Foundation and the 2005 Millennium Ecosystem Assessment,scientists have less than half of the basic ecological data they need to evaluate the status of ecosystems in the United States. Even fewer data are available for most other parts of the world..Ecologists call for a massive program to develop baseline data for the world's ecosystems.
根據2002年出版的生態學研究的海因茨基金會，以及2005年千年生態系統評估，發現在美國，科學家們只有不到一半的基本生態數據用以評估生態系統。對大多數世界其他地區而言，甚至只有更少的數據。生態學家呼籲為世界上的生態系統建立一個大規模基準數據。
