Building materials are generally procured from the Earth's strata or are end products of processed natural components. These resources are limited. Irresponsible extraction of natural compounds for building material manufacture can deplete these natural compounds from the earth. Moreover, extraction can cause harm to the natural habitat and biodiversity of the region where materials are extracted. Therefore, a project that uses minimum new building material and uses more of recycled materials is a more sustainable and responsible choice for a building material.
