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.
Concentrations of stratospheric ozone represent a balance, established over eons, between creative and destructive forces and this balance, or dynamic equilibrium, has been changed by human activity. Ozone is formed in the earth's stratosphere and is critical to life on earth as we know it. There is compelling scientific evidence that ozone is destroyed in the stratosphere and that some human-released chemicals are speeding up the breakdown of ozone in the atmosphere. CFCs, a human-developed compound, are particularly destructive to the breakdown of ozone in the atmosphere.
