Bal Tashchit (Do Not Waste)
She'elah: I want to host huge a Shabbat dinner for all of my friends. I could use my normal dishes and then use a lot of water to clean them. Or I could buy disposable dishes, that wouldn't use up water, but would take space in a landfill and couldn't be reused. What should I do? What will make less waste?
(י) וְלֹא הָאִילָנוֹת בִּלְבַד. אֶלָּא כָּל הַמְשַׁבֵּר כֵּלִים. וְקוֹרֵעַ בְּגָדִים. וְהוֹרֵס בִּנְיָן. וְסוֹתֵם מַעְיָן. וּמְאַבֵּד מַאֲכָלוֹת דֶּרֶךְ הַשְׁחָתָה. עוֹבֵר בְּלֹא תַשְׁחִית. וְאֵינוֹ לוֹקֶה אֶלָּא מַכַּת מַרְדּוּת מִדִּבְרֵיהֶם:
(10) And not only regarding trees, but even one who destructively breaks vessels or rips up clothing or tears down a building or seals up a spring or wastes food violates the Negative Commandment of “Do not destroy”. However, he only receives stripes for disobedience, in accordance with the Rabbis.
...אמר רב זוטרא האי מאן דמיכסי שרגא דמשחא ומגלי נפטא קעבר משום בל תשחית...
One who covers an oil lamp [causing the flame to burn inefficiently] or uncovers a kerosene lamp [allowing the fuel to evaporate faster] violates the prohibition of bal tashchit.
When you lay siege to a city for a long time, fighting against it to capture it, do not destroy its trees by putting an ax to them, because you can eat their fruit. Do not cut them down. Are the trees people, that you should besiege them? However, you may cut down trees that you know are not fruit trees and use them to build siege works until the city at war with you falls.
(ב) שרש המצוה ידוע, שהוא כדי ללמד נפשנו לאהב הטוב והתועלת ולהדבק בו, ומתוך כך תדבק בנו הטובה, ונרחיק מכל דבר רע ומכל דבר השחתה, וזהו דרך החסידים ואנשי מעשה אוהבים שלום ושמחים בטוב הבריות ומקרבים אותן לתורה, ולא יאבדו אפילו גרגיר של חרדל בעולם, ויצר עליהם בכל אבדון והשחתה שיראו, ואם יוכלו להציל יצילו כל דבר מהשחית בכל כחם
The root reason for this Mitzvah [bal tashchit] is known: ......... They will not destroy even a mustard seed in the world and they are distressed at every ruination and spoilage they see; and if they are able to do any rescuing, they will save anything from destruction, with all their power.
