Trees; you need them in the Amazon whether or not you can actually see them in the desert of Texas or Arabia. You need to breathe. As children of Abraham, you were called to be fruitful, multiply and to be good stewards. You have the technology and the insight to fulfill one ancestral purpose. Let your neighbor entertain you with his art projects and singing and don't mind if he feels good about it. He has a right to feel good as a child of God. You can strum and hum along too!
