There was a really good show on the History Channel a few days ago that pretty much covered just what you said. It started out with how the present day
oil deposits were formed from all living organic material that died millions of years ago when the Earth had a warming period so hot that you could have went swimming at the South Pole in comfort if you could have breathed the air. They showed some plant that still lives and they have fossilized leaves from it from way back then and by using that they could determine along with the rock just how much CO2 and other stuff was in the air. Oxygen was all drawn off and as this stuff sank or decayed and started to cover itself less CO2 was released and the oxygen begin to come back and ice also begin to form at the poles again. Now this took millions of years but it was a natural cycle. At the end of the show what they basically said is that what is living now and has been living for the past generations will be the next
oil deposits for whatever race occupies the planet in the distant future. I thought the show was very interesting as they had a lot of samples and data to back up what they said. So based on that, we will be in the next
oil deposits so we will be returning to the Earth what we have wasted during this period of time.
