That's a true, a very reasoned point. People should be more aware of all the other harms there are also, and smoking is just one of them.

Perhaps smoking is picked out for a few reasons. 1) There is no, absolutely no, benefit to society for it. Seriously, what's the benefit of someone smoking? They are usually more irritable (unless they're smoking), have various health problems associated with smoking, etc. 2) a lot of research has been done and most people agree that it's bad. 3) it's probably easier to get rid of, because we've been working on getting rid of it for a while.

Granted people should also spend a larger amount of time evaluating, for example, the bad foods they eat, or what kind of smog-producing car they drive.

Wow, to make a point and use false info is really showing the weekness od your argument.  A ton of fuel????   Gas weighs 8 pounds to the gallon I believe jet fuel is a little less.  Here is the statistic on a 747...  63,000  gallons fo fuel weighs slightly more than that.. Just think how much more powerfull your argument could have been if you had  the fact to back it up!!

747 Fun Facts

Parts

• A 747-400 has six million parts, half of which are fasteners.
• A 747-400 has 171 miles (274 km) of wiring and 5 miles (8 km) of tubing.
• A 747-400 consists of 147,000 pounds (66,150 kg) of high-strength aluminum.
• The 747-400 has 16 main landing gear tires and two nose landing gear tires.
• The 747-400 tail height is 63 feet 8 inches (19.4 m), equivalent to a six-story building.

Wings

• The 747-400 wing weighs 95,000 pounds (43,090 kg), more than 30 times the weight of the first Boeing airplane, the 1916 B&W.
• The 747-400 wing measures 5,600 square feet (524.9 m 2 ), an area large enough to hold 45 medium-sized automobiles.
• Four World War I vintage JN4-D "Jenny" airplanes could be lined up on each of the Boeing 747 wings.
• How much weight does an additional 6-foot (1.8-m) wingtip extension and winglet add to the 747-400 wing? None! A weight savings of approximately 5,000 pounds (2,270 kg) was achieved in the wing by using new aluminum alloys, which offset the weight increase of the wing tip extension and winglet

Engineering and Testing

• Seventy-five thousand engineering drawings were used to produce the first 747.
• The first 747 completed more than 15,000 hours of wind-tunnel testing.
• The original 747 flight test program, which led to the airplane's certification for commercial service in December 1969, used five airplanes, lasted 10 months and required more than 1,500 hours of flying.

Engine thrust has grown from 43,500 pounds (19,730 kg) per engine on the early 747s to as much as 63,300 pounds (28,710 kg) on the current model.

• The diameter of the 747 engine cowling is 8 feet 6 inches (2.6 m).

Fuel

• The 747-400ER can carry more than 63,500 gallons of fuel (240,370 L), making it possible to fly extremely long routes, such as Los Angeles to Melbourne, Australia.
• A 747-400 that flies 3,500 statute miles (5,630 km) and carries 126,000 pounds (56,700 kg) of fuel will consume an average of five gallons (19 L) per mile.
• The 747
