First we will compute the amount of meat necessary to feed every person on Earth \(110\) kilograms per year. In 2018 there are \(7.6 \times 10^9\) people on Earth.

\begin{equation*}
(5.5\times 10^9 \text{ people})\times (110 \text{ kg/person}) = 8.36 \times 10^{11} \text{ kg of meat}
\end{equation*}

Next we will compute the amount of grain needed to produce that much meat.

\begin{equation*}
(16 \text{ kg of grain/kg of meat})\times (8.36 \times 10^{11} \text{ kg of meat}) = 1.34 \times 10^{13} \text{ kg of grain}
\end{equation*}

Next we will see how many hectares of land are needed to produce that much grain.

\begin{equation*}
(1.34\times 10^{13} \text{ kg of grain})\div(6000 \text{ kg/hectare}) = 2.23\times 10^{11} \text{ hectares}
\end{equation*}

Finally, we will compute the amount of arable land available for grain production.

\begin{equation*}
0.11\times (13\times 10^9 \text{ hectares}) = 1.43\times 10^9 \text{ hectares}
\end{equation*}

Thus, even if we use every hectare of arable land to produce grain for livestock, we will not have enough to provide every person on Earth with \(110\) kilograms of meat per year.
