Because of transitional losses.
If you grow plants to feed to animals in order to eat the animals later, not all of the nutrients in the plants becomes nutrients in the meat.
Quite a lot is lost in the process.
So if humans eat plants directly, you've cut out a huge chunk of losses and made the process a lot more efficient.
The same goes for water. It takes a lot more water if you're going to first grow the crops, then raise the cattle, and then eat the meat. Remove the cattle from the chain and you need a lot less water as well.

European countries used their colonies to produce natural resources for the benefit of the mother country
Some examples of countries that produce more food than they consume include the United States, Canada, Australia, and Brazil. These countries have large agricultural sectors and benefit from favorable climates and extensive farming land, allowing them to export food and agricultural products to other nations.
Rwanda is a small, impoverished country that contributes little to global warming and can therefore do little to stop it. Rwanda is really at the mercy of larger and wealthier carbon-emitting countries like the United States, China and Britain. If these countries act responsibly, then Rwanda will benefit.
