There are probably already too many people on the planet.
We need to continue to decrease the growth rate
of the global population.
The planet can't support many more people.

If Gazelles need water and grass
and Cheetahs need water and Gazelles
and an abundance of sustenance leads to more Gazelles,
should more Gazelles and water lead to more Cheetahs?
If too many Gazelles relative to water and grass lead to fewer Gazelles,
do fewer Gazelles = fewer Cheetahs?
Population, when unchecked,
increases in a geometrical ratio.
Subsistence only increases in an arithmetical ratio.

Suggested populations could increase faster than food supplies
