The idea that the world is overpopulated is total, complete, and utter crap.
Watch, I'll prove it to you using 4th or at most 5th grade math. I'll even use algebra to make it seem neat.
X / Y = Z
Z > A
X is the world population
Y is the area (in square miles) of the state of Texas
Z is the resounding population density if you were to put the entire world into Texas
A is the population density of New York City.
X = 6,775,235,700
Y = 268,581 sq mi
Z = 27,532 people/sq mi
A = ?
Lets run the problem!
6,775,235,700 people/ 268,581 sq mi = 25,226 people/sq mi
25,225 > 27,532
The above inequality is false.
Therefore, the world is not over populated.
Look, one world problem solved by basic math. yay.
