7 billion

7 billion is allot. Especially 7 billion people. This is the amount of people that are currently living on earth. So many things changed in so little time. We were once faced with the challenge of losing our population but now we face the challenge of gaining to much of our population. Everytime we are faced with a challenge, we succeed and improve, but after that we are faced with a more difficult challenge. No matter what, all we can do is improve. What do you think will be our next number? 9 billion? 10 billion? 20 billion? Like I said, all we can do is improve.
