Unripe Avocado |ethylene gas|

This is the way and avocado should be on right and hard like a rock. Avocado is often harvested hard to see if it is to keep it in the dark place or in a bag or wrapping newspaper. Put a fruit in a paper bag and it will magically ripen quicker than outside of the bag. What really happens is that the paper bag traps the ethylene gas that’s produced by the fruit during its ripening process.
