How does conservation of resource also reduce pollution and protects habitat?

If you conserve, or save a resource, then that resource does not have to be manufactured as much because we are re-using it. For example, if we conserve paper, recycle carboard and newspaper, then there is less of a need for the cutting of trees and manufacturing of the paper products. This protects the forest habitat. Also, the manufacturing process creates pollution, so it also cuts back on pollution as well. The same concept applies for conserving plastics, oil, water, etc.
