The space shuttle turned up just right on its target according to Marcia Dunn of Associated Press. Cheers! It is another joyful achievement worth recognition. But, in the midst of this success, let us look at the picture ones more and see the cloud of smoke emitted at the space shuttles take off. How much pollutant do you think has it blown up into the atmosphere? After all, the machine is powered by kerosene. How can a little effort of greening, non-smoking, throwing your trash on the right places, and recycling, compare to a massive emission? Indeed the prize of development is colossal.
