Why is the ozone layer important for Earth's life forms? The ozone layer is important for Earth's life forms because it protects Earth from harmful ultraviolet radiation. This made the environment able to support more complex life forms. 2.) Describe the role of cyanobacteria in changing Earth's early atmosphere. Cyanobacteria helped in changing Earth's atmosphere by adding an abundance of oxygen to it. To this day cyanobacteria's account for 20% to 30% of photosynthesis today.
Tropospheric and Stratospheric Ozone. Perhaps the most common misunderstanding about ozone comes from the fact that, in certain places, ozone is essential to life. When ozone is high above the Earth in the stratosphere, it helps protect life on the ground from solar radiation by scattering incoming ultraviolet rays from the sun. The skin cancer epidemic in Australia, for example, is related to a hole in the stratospheric ozone. But when ozone is closer to the ground (the troposphere), it enters our respiratory system and can cause a variety of mild to severe health effects.
