The planet's surface hasn't been hospitable for a very long time, so life on Mars probably had no time to evolve beyond simple microbes.
He spends his spare time educating key decision makers on why fast nuclear power such as the IFR can help avert a climate crisis (by making carbon-free electricity cheaper than power from coal plants) so that his 3 daughters can grow up on a planet that is hospitable for human life.

Expanding this number to cover the amount of land estimated to be hospitable habitat for these animals (about half the land on Earth at the time), the researchers end up with more than 550 million tons (500 million tonnes) of methane produced every year.
