For example, die casting a part from recycled aluminum requires 95 percent less energy than using primary metal. Saving energy means less carbon dioxide emitted into the atmosphere. Recycling paper products such as newspapers and cardboard saves trees. The average Canadian family uses up to 12 trees every year in paper products. Most of this ends up in garbage dumps and landfill sites.
Trees play an important role in regulating the amount of carbon dioxide in the atmosphere.
Saving trees helps stop global warming. More than half of all solid waste collected in Canada is made up of consumer or household garbage. Reducing the amount of garbage ending up in landfill sites can have a positive effect on the amount of methane which is released into the atmosphere.
