What If Every Insect On Earth Disappeared?

Insects are crucial to the survival of bird and amphibian species, as they are an essential part of the food chains. Over 75% of the world’s food crops are pollinated by insects, which are divided into three parts: the head, thorax, and abdomen. Without insects, we would not have access to food sources such as fruits, vegetables, and seeds, which are used to cultivate plants.

If all insects vanish, the Earth would become lighter, but the effects would be disastrous and cause the end of almost all life on Earth. Even removing a small number of important invertebrate species could trigger a biosphere collapse with unknown but likely awful consequences. Frogs would begin eating small fish, tadpoles, and each other with a much greater frequency.

A world without bugs would mean fewer foods to eat, products to use, and a huge decrease in scientific and medical discovery. The hypothetical scenario of all insects disappearing would lead to catastrophic impacts on ecosystems and biodiversity, profoundly affecting plant and animal life.

Insects are an essential part of ecosystems, and their disappearance could lead to the collapse of civilization and ecosystems worldwide. Without dung beetles, dermestids, and pollinators, the Earth would become lighter, and the survival of the human race would be at risk.

What If Cockroaches Went Extinct?

A significant absence of cockroaches could destabilize the nitrogen cycle, a critical ecological process. Cockroaches consume decaying organic matter, trapping nitrogen that gets released back into the soil through their waste. Eliminating these pests might seem appealing; however, they are integral to various ecosystems. Their absence would have cascading effects, potentially leading to the extinction of wasp species that rely on cockroaches as a food source and impacting animals and birds that prey on them. Cockroaches have existed for over 300 million years, showcasing their adaptability and resilience in fluctuating environments.

Predicting the ecological consequences of cockroach extinction is challenging. The impact could range from minor shifts to severe ecological disruptions, affecting numerous animal populations that depend on them indirectly for food.
