Why do bananas ripen faster when placed with other fruits?

Why do bananas ripen faster when placed with other fruits? Have you ever noticed that bananas turn black easily when left for a while, and even cause nearby fruits to ripen faster? This is actually related to a gas called 'ethylene'. As bananas mature, they release ethylene, a gas that accelerates fruit ripening. When bananas are placed with fruits like apples, kiwis, and avocados, more ethylene accumulates, potentially causing them all to ripen faster together. So, if your fruits aren't ripe yet, keeping them together can sometimes help them ripen more quickly. However, if they are already ripe, it's best to store them separately, especially bananas, to prevent other fruits from becoming too soft too quickly. It turns out fruits really do 'influence' each other; you weren't just imagining it.
