KNOXVILLE, Tenn. (WVLT) -- You're one of seven billion people and counting on Planet Earth. But just how many is that?
Seven billion people is enough to fill Neyland Stadium and more than 68,000 just like it. If you tried to count that high, it'd take you 30 years.
"The increase has been phenomenal in the last 15, 20 years. And whether or not that continues is the big question," said Randy Gustafson.
Gustafson, director of the State Data Center, says it was 1800s when we hit just one billion.
And it only took us 12 years to go from six billion people to seven.
Can the earth's resources keep up with its inhabitants?
"There is a very real dangers in some parts of the water. Not enough water. Not enough food," said Gustafson.
Tennessee's growth has matched that around the globe.
"She definitely was ready to come out. She was waiting no longer," said new mom Jennifer Ladd.
Lydia Ladd was born Sunday morning, when it was already October 31 halfway around the world. She could be the 7 billionth baby.
"The first thing that comes to my mind is to be fruitful and multiply. That's the first thing that came to my mind," said Ladd.
Jennifer and dad Luke say they are celebrating, and trying figure just what a number that size means. But they know their baby girl is in good hands.
"I believe that He has a plan for her. As far as worried about what her future looks like. I'm not worried. I know that He's got it under control," said Ladd.
