What happens if there is no birds in sky?

If there were no birds in the sky, it would indicate significant ecological imbalances, impacting the food chain and biodiversity. Birds play crucial roles in pollination, seed dispersal, and pest control, so their absence could lead to overpopulation of insects and a decline in plant diversity. Additionally, many animals and humans rely on birds for food and cultural significance, which would disrupt various ecosystems and economies. Overall, the absence of birds would signify broader environmental issues and have cascading effects on nature and human life.
