Today’s daf yomi (Tamid 28-29) discussed the type of wood used to burn the sacrifices on the alter. The fruit bearing trees, such as olive trees, are prohibited.

Is any futher proof needed that natural beauty, the health of the land and a sense of the aesthetic should be always on the mind of a Jew.
