&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The world depends on materials such as [[metal]], [[glass]], [[plastic]], [[wood]], and so many more. All of these have an environmental impact, and involve some human [[labor]].&lt;br /&gt;
&lt;br /&gt;
How do we weigh the benefits of any ''green solution'' against the materials it uses?&lt;br /&gt;
&lt;br /&gt;
==Research needed==&lt;br /&gt;
&lt;br /&gt;
For each material, consider&lt;br /&gt;
* The [[energy]] it takes to produce it&lt;br /&gt;
* The [[pollution]] it takes to produce it {{x|If there are less polluting ways, are there tradeoffs such as needing more energy?}}&lt;br /&gt;
* Other considerations&lt;br /&gt;
** For organic materials&lt;br /&gt;
*** For products (such as wood), consider the ''land*time'' needed to grow them&lt;br /&gt;
*** For [[biomass waste|byproducts]], consider the ''inherent supply''&lt;br /&gt;
** For inorganic materials (such as metal)&lt;br /&gt;
*** Mineral reserves&lt;br /&gt;
*** Land disturbed by mining {{x|You can define ''disturbed'' in more than one way; for example, ''area dug up'' vs ''surrounding area polluted''.}}&lt;br /&gt;
&lt;br /&gt;
Most imporantly, consider the impacts ''per unit'' of material.&lt;/div&gt;</summary>
