What reasons besides being necessary for the methane cycle, can you think of that might
Stella [2.4K]

Titan's rivers, lakes, and seas of liquid methane and ethane could provide a habitable environment on the moon's surface, though any life there would most likely be very different from life on Earth.

Methane gas is effective at trapping heat and burns quickly. As a result, methane is one of the most important human fuels. Furthermore, methane in the atmosphere helps to regulate the Earth's climate.

Over the first 20 years after it enters the atmosphere, methane has more than 80 times the warming power of carbon dioxide. Even though CO2 has a longer lasting effect, methane drives warming in the short term. Methane from human activity is responsible for at least 25% of today's global warming.

As a result, methane not only contributes to global warming directly, but also indirectly through the release of carbon dioxide.
