What If: Earth’s Insects Suddenly Vanished Overnight
We might not like the creepy crawlies, but insects are a massive part of our world’s ecosystem. There are literally trillions of them across numerous different species lines all over the world. Each one does a critical job for our environment so much so, regions have felt problems when specific insects types dropped off. Therefore, when we think about scary scientific what-ifs, losing all insects on Earth is near the top of the list. Roughly 80% of all plants on Earth are flowering.
That means they must go through pollination. Who ensures this happens? Insects, such as bees and butterflies. Without insects that assist in pollination, most of the world’s plant life would die. That would guarantee a vast food chain collapse. This collapse would kill most mammals and birds, and many of them also use things like trees for homes. Those trees would begin to die off and all the fruits or vegetables they have. Literally, without insects, humans will be extinct within a few years max.
