How does recycling paper plastic and aluminum help to save the environment?

If paper, plastic and aluminum are not recycled they add to the huge amount of material in landfill dumps all over the world. Plastic and aluminum will remain there for years and years.

Recycling the materials above uses less energy than producing them from fresh materials, so there is a reduction in carbon emissions into the atmosphere, less cost to consumers, and smaller landfill dumps.

if we don't recycle plastic than we will have to keep making more and more of it and to make plastic you have to use lots and lots of chemicals, especially oil.
