I recently saw a six-year-old child with a chart in his hands at the gates of his school. He was looking at some workers nearby who were cutting trees for road construction. The chart had a tree drawn on it and read the message: ‘Save trees, trees give us oxygen and without oxygen we can’t live’. He had got an A+ grade on the chart. Soon, his parents came and while leaving, his eyes were continuously on those workers. I wondered: “What did the child learn today?” But it’s true: Without oxygen, we can’t live, save trees!
