Answer 1

due to increased exposure to harmful UV rays from the sun. Additionally, there would likely be a negative impact on plant and animal life, as increased UV radiation can harm ecosystems and disrupt food chains. The ozone layer plays a crucial role in protecting life on Earth from the harmful effects of UV radiation, so if it were to break down completely, the consequences could be severe.
