Several years ago a NASA spacecraft passed the planet Mercury. A transmitted photo clearly revealed the effect of meteor strikes on the surface. Their impacts of Earth were not so apparent from the Space Shuttle, unless you know where to look like in the Yucatan or polar areas, but most astronomers are more concerned with incoming asteroids or comets as a threat to life on Earth greater than Man.
“Civilization killers” of 1 kilometer, or about 3,300 feet are veering closer and closer to Earth due to the planet’s increased magnetic pull. Some have missed our planet by 29.8 million miles or a third the distance to the Sun. Smaller objects can crash into onEarth with various degrees of destruction from not being able to watch TV to the flattening of Kansas and something as small as a semi-trailer could achieve that effect.
NASA has reckoned such events occur once every 300 years, but the odds favor an ocean landing, since Earth is 2/3 water.
One way to defuse this problem would be for Americans to lose weight, since the Earth’s gravity pull is directly effected by the mass of the planet. NASA has been warned about the dangers of obesity, now is the time to act before it’s too late.
Not only is losing weight for the planet, it’s good for you.

Every little bit helps.
