W hav only on globDon't you s th havy smoks from th big chimnys? Don't you smll th gas from th motors all around th strts? W'v got much dirtir air! Th icburgs ar mlting from th warmr wintr bcaus of th air pollution!
Don't you s thr ar lss livs in th watr? Don't you s that w must pay highr cost in watr procssing? W'v got much darkr watr running around! Th ocans ar in grat dangr.
Don't you s th montains gtting bald? Don't you s our ground bcoming hollow? W'v bn xhausting th rsourcs bnath th arth. Our grandchildrn will liv on nothing.
W hav only on glob. Trasur th mothr natur!
