How Much Time Do We Have Left?

Geologists economists have been trying to answer that question for a long time. In the early 19 hundreds, we were discovering a ton of oil fields. But by about the year 19 30, that actually started to decline. The second part of that is that we keep finding new types of oil. They're just a lot more difficult to extract. And so i'm in a touch on both of these things here for a inute so that they make sense.
