How Can Matter Change?
問題怎麼改變？
We Cannot Create or Destroy Matter
We can change elements and compounds from one physical or chemical form to another, but we can never create or destroy any of the atoms involved in any physical or chemical change. All we can do is rearrange the elements and compounds into different spatial patterns (physical changer) or combinations (chemical changes). These statements, based on many thousands of measurements, describe a scientific law known as the law of conservation of matter:when a physical or chemical change occurs, no atoms are created or destroyed.
This law means there is no "away" as in "to throw away." Everything we think we have thrown away remains here with us in some form. We can reuse or recycle some materials and chemicals but the law of conservation of matter means we will always face the problem of what to do with some quantity of the wastes and pollutants we produce.

我們不可能創造或毀壞問題
我們可以從一個物理或化工形式改變元素到另一種化合物，但是我們不可以創造或毀壞在任何物理或化学变化介入的其中任一個原子。 我們可以做的所有是重新整理元素和化合物入不同的空间图案(物理更換者)或組合(化学变化)。 這些聲明，根據許多數以萬計測量，描述叫作物质守恒定律的科學法律：当物理或化学变化发生时，原子沒有被創造也沒有被毀壞。
這法律意味沒有去的作为投擲。 我們認為的一切我們投擲了保持這裡與我們以某种形式。 我們可以重複利用或回收有些材料和化學製品，但是物质守恒定律我們永远將面對的問題如何处理廢物和汙染物的某一數量我們生產的手段。
問題討論
因物質守恆定律,當前我們應該探討的是如何將廢棄物回收再利用.或者盡量將物品作容易分解的材質這樣才不會繼續增加地球的汙染.
