Is the earth running out of oil?
Globally, we currently consume the equivalent of over 11 billion tonnes of oil from fossil fuels every year. Crude oil reserves are vanishing at a rate of more than 4 billion tonnes a year – so if we carry on as we are, our known oil deposits could run out in just over 53 years.
What will happen in 100 trillion years?
Every single day more than 400 million stars are formed. That’s about 4600 stars per second. But in 100 trillion years, Galaxies will run out of fuel and the formation of stars will stop. … As time passes, those remaining stars will also run out of fuel and universe will get colder and darkness will take over.

What happens if natural resources run out?
Plants. Like trees, plants feed us and give us the oxygen we breathe—and if they were to run out, humans and animals would starve and suffocate. According to New Scientist, oxygen would remain in the atmosphere for quite a while, but we would run out of food long before we’d run out of air.
