The way most people live and eat and work is in a way that essentially means that they have been kicked out of the Garden of Eden.

We are emitting gases and toxic substances that foul our own nest. Very few animals foul their own nests, but we as supposedly intelligent beings do foul our own nest and poison our own young; with carbon dioxide emissions, toxins in our homes, food, air, water and ground.
Our housing is not sustainable currently. By living the way we do, we have kicked ourselves out of the Garden of Eden. We live in structures that cost an arm to heat, a leg to cool and a fortune to maintain. Then they cost more to destroy when we are done with them, and their toxic residue takes up precious room in dumps. Our houses and business structures degrade our health, harm our children and employees and the environment through carbon emissions, out gassing, radiations, toxic materials and more.
