Of course,simulations and projections made with ecosystem models are no better than the data and assumptions used to develop the models.Ecologists must do careful field and laboratory research to get baseline data, or beginning measurements of variables being studied.They also must determine the relationships among key variables that they will use to develop and test ecosystem models.

We 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.
理所當然,模擬和計畫使得這生態系統模型和用來建立此模型的資料和假設一樣好，生態學家必須仔細地調查或是實行實證研究以得到基本資料或是衡量欲研究之變數，他們也必須決定他們建立此模型和測試此模型的關鍵變數和模型本身之間的關係。

我們必須了解世界上的生態系統是否健全

我們需要對於世界上所有生態系統的基本資料以便了解生態系統是如何改變和建立對於預防或減緩物種之減少的策略
