don't you see the heavy smokes from the big chimneys? don't you smell the gas from the motors all around the streets? we've got much dirtier air! the iceburgs are melting from the warmer winter because of the air pollution!

　　don't you see there are less lives in the water? don't you see that we must pay higher cost in water processing? we've got much darker water running around! the oceans are in great danger.

　　don't you see the montains getting bald? don't you see our ground becoming hollow? we've been exhausting the resources beneath the earth. our grandchildren will live on nothing.

　　we have only one globe. treasure the mother nature!
