How does your body burn 2000 calories a day without any effort, but running a mile only burns 100 calories?

There are 2 things:
1. Keeping you alive takes a lot of effort. Breathing, pumping blood, growing hair, sweating and many other things. It all takes effort. And, most of the body systems cannot stop. And they are not allowed to fail either. It all has to function or you are, in many cases, dead or severely sick.
2. There is a perception issue here too. 100 is more than you think. It is 5%.
I’ll you use the numbers you have provided. 100 cal is a 5% increase in your(2k) caloric need. Assuming you run something like 3 miles instead(which is a bit more reasonable for people who workout regularly) that is %15 increase over your base maintenance level. Think of having a raise of 15% to your salary or having to pay 15% more for your groceries.
