Don't be mean, go Green!

छायामन्यस्य कुर्वन्ति
तिष्ठन्ति स्वयमातपे ।
फलान्यपि परार्थाय
वृक्षाः सत्पुरुषा इव ॥

Trees make shade for others, even by standing themselves in Sun. They also provide fruits for others to enjoy. Trees are indeed, like good people.

Don't be mean, go Green!
The best time to plant a tree is twenty years ago. The second best time is now.
