One with compassion, love forbearance, sympathy and sacrifice alone is a true human being. But in modern man, such sacred qualities have become scarce. Man originated from nature. Earth sustains life. Sun give light.
Trees give oxygen.
Water quenches our thirst. And air helps us to live. Having been born out of and brought up by nature, man should practice and propagate the ideals set by nature. Birds, animals and trees follow nature and lead an ideal life. Trees inhale poisonous carbon dioxide and exhale life supporting oxygen.
