Recycling is an ongoing part of the Zoo's commitment to conservation.
When we throw things away, we make an impact on the environment – that waste has to go somewhere, there is no "away" - and we lose the natural resources and the energy that were used to manufacture those items. Most of these natural resources cannot be replaced – for example, the rocks (ore) from which metals are mined. So if we keep on using and throwing away resources in this way, eventually they will run out. Aluminum is the most valuable material in the trash stream. Recyclable materials have to be separated out from the rest of the trash and sent to reprocessors, companies who turn the materials back into usable products.
