8-3 Science & Siyyum-Better Together Earth Day/Technion 2017
To whom does the world belong and what is our relation to it?
וַיְבָ֣רֶךְ אֹתָם֮ אֱלֹקִים֒ וַיֹּ֨אמֶר לָהֶ֜ם אֱלֹקִ֗ים פְּר֥וּ וּרְב֛וּ וּמִלְא֥וּ אֶת־הָאָ֖רֶץ וְכִבְשֻׁ֑הָ וּרְד֞וּ בִּדְגַ֤ת הַיָּם֙ וּבְע֣וֹף הַשָּׁמַ֔יִם וּבְכָל־חַיָּ֖ה הָֽרֹמֶ֥שֶׂת עַל־הָאָֽרֶץ׃

And God blessed them and God said to them, ‘Be fruitful, and multiply, and fill the earth and master it; and rule the fish of the sea, the birds of the sky, and all the living things that creep on earth.’

לְדָוִד מִזְמוֹר: לַה' הָאָרֶץ וּמְלוֹאָהּ, תֵּבֵל וְיֹשְׁבֵי בָהּ.

A Psalm of David. __________________ _______________________, the world and its inhabitants.

(טז) הַשָּׁמַ֣יִם שָׁ֭מַיִם לַה' וְ֝הָאָ֗רֶץ נָתַ֥ן לִבְנֵי־אָדָֽם׃

(16) The heavens belong to the LORD, but the earth He gave over to humanity.

The previous two verses seem to contradict one another: To whom does the earth belong? How could you harmonize them?

וַיִּקַּח ה' אֱלֹקִים אֶת הָאָדָם וַיַּנִּחֵהוּ בְגַן עֵדֶן לְעָבְדָהּ וּלְשָׁמְרָהּ.

And the LORD God took the man and placed him in the garden of Eden, _________________________________.

Sustainability in the Talmud
The stories of Honi the Circle Maker (third chapter of Masekhet Ta’anit)
Honi the Wise One was also known as Honi the Circle Maker. By drawing a circle and stepping inside of it, he would recite special prayers for rain, sometimes even argue with God during a drought, and the rains would come. He was, indeed, a miracle maker. As wise as he was, Honi sometimes saw something that puzzled him. Then he would ask questions so he could unravel the mystery.
One day, Honi the Circle Maker was walking on the road and saw a man planting a carob tree. Honi asked the man, "How long will it take for this tree to bear fruit?"
The man replied, "Seventy years."
Honi then asked the man, "And do you think you will live another seventy years and eat the fruit of this tree?"
The man answered, "Perhaps not. However, when I was born into this world, I found many carob trees planted by my father and grandfather. Just as they planted trees for me, I am planting trees for my children and grandchildren so they will be able to eat the fruit of these trees."
Bal Tash'hit - The Jewish Principle of not wasting

כִּי תָצוּר אֶל עִיר יָמִים רַבִּים לְהִלָּחֵם עָלֶיהָ לְתָפְשָׂהּ לֹא תַשְׁחִית אֶת עֵצָהּ לִנְדֹּחַ עָלָיו גַּרְזֶן כִּי מִמֶּנּוּ תֹאכֵל וְאֹתוֹ לֹא תִכְרֹת כִּי הָאָדָם עֵץ הַשָּׂדֶה לָבֹא מִפָּנֶיךָ בַּמָּצוֹר.

רַק עֵץ אֲשֶׁר תֵּדַע כִּי לֹא עֵץ מַאֲכָל הוּא אֹתוֹ תַשְׁחִית וְכָרָתָּ וּבָנִיתָ מָצוֹר עַל הָעִיר אֲשֶׁר הִוא עֹשָׂה עִמְּךָ מִלְחָמָה עַד רִדְתָּהּ.

When in your war against a city you have to besiege it a long time in order to capture it, you must not destroy its trees, wielding the axe against them. You may eat of them, but you must not cut them down. Are trees of the field human to withdraw before you into the besieged city? Only trees that you know do not yield food may be destroyed; you may cut them down for constructing siegeworks against the city that is waging war on you, until it has been reduced.

An ecological parable

וּלְאָדָם אָמַר כִּי שָׁמַעְתָּ לְקוֹל אִשְׁתֶּךָ וַתֹּאכַל מִן הָעֵץ אֲשֶׁר צִוִּיתִיךָ לֵאמֹר לֹא תֹאכַל מִמֶּנּוּ

אֲרוּרָה הָאֲדָמָה בַּעֲבוּרֶךָ בְּעִצָּבוֹן תֹּאכֲלֶנָּה כֹּל יְמֵי חַיֶּיךָ.

וְקוֹץ וְדַרְדַּר תַּצְמִיחַ לָךְ

וְאָכַלְתָּ אֶת עֵשֶׂב הַשָּׂדֶה.

בְּזֵעַת אַפֶּיךָ תֹּאכַל לֶחֶם ...

To Adam He said, "Because you ______________ your wife's voice but ate of the tree about which I commanded you, 'You shall not eat of it,'

Cursed be the ground because of you;

By toil shall you eat of it
All the days of your life:
Thorns and thistles shall it sprout for you. But your food shall be the grasses of the field;
By the sweat of your brow shall you get bread to eat ..."
The environmentalist imperative in the Midrash
בשעה שברא הקדוש ברוך הוא את אדם הראשון, נטלו והחזירו על כל אילני גן עדן, ואמר לו: ראה מעשי כמה נאים ומשובחין הן, וכל מה שבראתי, בשבילך בראתי, תן דעתך שלא תקלקל ותחריב את עולמי, שאם קלקלת אין מי שיתקן אחריך.

At the time that the Holy One created the first man, He introduced him to every tree in the Garden of Eden, and said to him, ‘See how wonderful and pleasant these trees are. And all of this I have created for you; therefore take great care that you do not damage and destroy My world, for if you do there is no one else to put right what you have destroyed.’

(5) tanned ram skins, dolphin skins, and acacia wood;

(ז) ועצי שטים. וּמֵאַיִן הָיוּ לָהֶם בַּמִּדְבָּר? פֵּרַשׁ רַבִּי תַּנְחוּמָא: יַעֲקֹב אָבִינוּ צָפָה בְּרוּחַ הַקֹּדֶשׁ שֶׁעֲתִידִין יִשְׂרָאֵל לִבְנוֹת מִשְׁכָּן בַּמִּדְבָּר, וְהֵבִיא אֲרָזִים לְמִצְרַיִם וּנְטָעָם, וְצִוָּה לְבָנָיו לִטְּלָם עִמָּהֶם כְּשֶׁיֵּצְאוּ מִמִּצְרָיִם:

(יט) וַיֹּ֨אמֶר ה' אֶל־מֹשֶׁ֗ה אֱמֹ֣ר אֶֽל־אַהֲרֹ֡ן קַ֣ח מַטְּךָ֣ וּנְטֵֽה־יָדְךָ֩ עַל־מֵימֵ֨י מִצְרַ֜יִם עַֽל־נַהֲרֹתָ֣ם ׀ עַל־יְאֹרֵיהֶ֣ם וְעַל־אַגְמֵיהֶ֗ם וְעַ֛ל כָּל־מִקְוֵ֥ה מֵימֵיהֶ֖ם וְיִֽהְיוּ־דָ֑ם וְהָ֤יָה דָם֙ בְּכָל־אֶ֣רֶץ מִצְרַ֔יִם וּבָעֵצִ֖ים וּבָאֲבָנִֽים׃

(19) And the LORD said to Moses, “Say to Aaron: Take your rod and hold out your arm over the waters of Egypt—its rivers, its canals, its ponds, all its bodies of water—that they may turn to blood; there shall be blood throughout the land of Egypt, even in vessels of wood and stone.”

(יט) אמר אל אהרן. לְפִי שֶׁהֵגִין הַיְאוֹר עַל מֹשֶׁה כְּשֶׁנִּשְׁלַךְ לְתוֹכוֹ, לְפִיכָךְ לֹא לָקָה עַל יָדוֹ לֹא בַדָּם וְלֹא בַצְפַרְדְּעִים, וְלָקָה עַל יְדֵי אַהֲרֹן (שמות רבה):

(19) אמר אל אהרן SAY TO AARON — Because the river had protected Moses when he was cast into it, it was not struck by him, neither at the plague of blood nor at that of frogs, and it was struck by Aaron instead (Shemot Rabbah 9:10).
