Do you mean the Gros Michel banana ? It went commercially extinct in the '60s due to a fungus. So, yeah, probably not coming back. Sadly, the Cavendish banana is also subject to the same fungus so may also get wiped out at some point in the future.

But Race 4 (also known as TR4 or fusarium wilt), the new version of Panama disease that started affecting crops in the subtropics in the 1980s and wiping them out, has since moved to infect crops in the Vietnam, Laos, Pakistan, India, Mozambique, and Australia. In 2019, Colombia declared a national disaster when it was discovered there. As it inches closer to Latin America, the likelihood of losing the Cavendish increases.

Plants need us animals to turn that oxygen they produce back into carbon dioxide for them.
