One example of the importance of ions in our study of environmental science is the nitrate ion, a nutrient essential for plant growth. Figue2-3 shows measurements of the loss of nitrate ions from the deforested area in the controlled experiment run by Bormann and Likens. Chemical analysis of the water flowing through the deams of the cleared forest area showed a 60-fold rise in the concentration of nitrate ions compared to water running off of the uncleared forest area.
一個重要性的離子例子在我們環境科學的研究內是那些硝酸鹽離子，一個必要的營養在植物生長時 。

Some matter consists of one element ,but most matter consists of compounds : combinations of two or more different elements held together in fixed proportions. For example, water is a compound made of the elements hydrogen and oxygen, which have chemically combined with one another.
一些物質由一種元素組成，但是大多數物質由化合物組成︰ 兩種或更多不同的元素在固定的比例結合在一起。 例如，水是由元素氫和氧組成的化合物，是已經和另一個化學的結合。

Pollution prevention (front-of-the-pipe)and pollution cleanup (end-of-the-pipe)solutions are both needed. But environmental scientists, some economists, and some major companies want us to put more emphasis on prevention because it works better and in the long run is cheaper than cleanup. We disscus this further in Chapter 17.
污染預防和汙染清除方法是同時需要的~但是環境學家,一些經濟學家,再加上一些主要的公司想要我們更強調預防,因為他正常工作並且歸根究底比清除便宜~

The search for solutions often involves conflicts.Thus, another component of the shift toward sustainability involves trying to resolve these conflicts by making trade-offs, or compromises.
解決的辦法經常包含衝突~因此,向永續性的另一個變化因素包含試著藉由做交換或妥協來解決這些衝突~
