The largest fast food chain in the history of mankind is...well...massive.
With more than 34,000 locations worldwide, McDonald's is awesome and awful at the same time.
Ignoring the politics, let's look at the physics!
On an average day, 300,000,000 people around the world will consume food from McDonald's.
The average amount of calories on the McDonald's menu is 500 calories per meal.
Let's say that each person buys a meal. Here's where it gets gross.
Worldwide, humans consume 1.5e11 calories of McDonald's, PER DAY.
That's 630 GJ (giga-joules).
That's also 1111111111 twinkies. Or, if you're healthy, 1.875e10 cucumbers, or 641025641 avocados.
We eat a lot of food, and McDonald's could either be described as a marvel of engineering or an evil corporation. Maybe it's both.
