Pollution and Materials that pollute
Buildings are a major source of air pollution, causing depletion to the ozone, acid rain and health issues.
Sources within buildings include the materials and processes used to build them, furnishings, paints, air conditioning and smoke from stoves and fireplaces.
Two other major influences are the chemicals emitted from insulating materials; and the supply of energy to the home which requires burning fossil fuels.
Consider natural ventilation systems, wood burning stoves, locally sourced materials, non- toxic paints and natural insulation materials.
